3. Notes & Tips​

Character Guidelines

  • Minimum requirement: Username must contain at least 2 characters to be accepted
  • Maximum allowance: Names can contain up to 50 characters including spaces and special characters
  • International support: Unicode characters are supported for global naming conventions
  • Case preservation: The application maintains exact capitalization as entered by the user

Display Considerations

  • Truncation behavior: Names exceeding 20 characters display with ellipsis ("...") in compact interface elements
  • Full name access: Complete names remain accessible in expanded profile views regardless of display truncation
  • Formatting retention: Spaces, capitalization, and special characters are preserved exactly as entered

Technical Synchronization

  • Firebase integration: Name changes sync through Firebase Authentication for cross-device consistency
  • Real-time updates: Changes appear immediately throughout the application interface
  • Offline capability: Name changes queue for synchronization when internet connectivity is restored
  • Backup considerations: Previous usernames are not stored; each change overwrites the previous value

4. FAQ​

Username Requirements & Validation

What characters are allowed in usernames?**​

Usernames support a comprehensive character set including:

  • Alphabetic characters (A-Z, a-z) in all supported languages
  • Numeric characters (0-9)
  • Spaces and common punctuation marks
  • Special characters and symbols
  • Unicode characters for international names
  • Emojis and other Unicode symbols are generally supported

Why can't I save a username with only one character?**​

The minimum length requirement of 2 characters ensures proper identification and prevents display issues in interface elements. Single characters may cause confusion in user recognition and system processing.

What happens if I exceed the 50-character limit?**​

The input field prevents typing beyond 50 characters. If you attempt to paste text exceeding this limit, only the first 50 characters will be accepted, and you'll receive a warning about the character limit.

Can I use my email address as my username?**​

Yes, email addresses are permitted as usernames since they typically fall within character limits and contain only supported characters.

Edit Process & Interface Issues

The edit dialog doesn't open when I tap my username.**​

Try these troubleshooting steps:

  • Ensure you're tapping directly on the username text or edit icon
  • Check that you're logged into a valid account
  • Restart the application and attempt again
  • Verify you have internet connectivity for the edit interface to load
  • Update the app if you're using an older version

I see "Name cannot be empty" error when trying to save.**​

This error occurs when:

  • The input field is completely blank
  • Only spaces or invisible characters are entered
  • The text was accidentally deleted before saving
  • Solution: Enter at least 2 visible characters and ensure the field contains actual text content

My username change isn't saving and shows "Failed to update name."**​

Common causes and solutions:

  • Poor connectivity: Verify stable internet connection and retry
  • Authentication issues: Log out and log back in, then attempt the change
  • Server synchronization problems: Wait 2-3 minutes and retry the update
  • Character encoding issues: Try using simpler characters without special symbols
  • Account restrictions: Ensure your account has full editing privileges

The character counter shows incorrect numbers.**​

Character counting discrepancies may occur with:

  • Special Unicode characters that occupy multiple character spaces
  • Emojis counting as multiple characters despite appearing as single symbols
  • Copy-pasted text containing hidden formatting characters
  • Solution: Type the username manually rather than copying from other sources

Synchronization & Display Issues

My new username appears on some screens but not others.**​

Incomplete synchronization can occur due to:

  • Cached data in certain app sections requiring refresh
  • Background processes still updating various interface elements
  • Solution: Force-close and restart the application, or pull down to refresh affected screens

My username looks different on different devices.**​

Cross-device discrepancies may result from:

  • Delayed synchronization between devices
  • Different app versions displaying names differently
  • Network connectivity issues during the update process
  • Solution: Ensure all devices have internet connectivity and the latest app version

Long usernames are cut off with "..." - can I see the full name?**​

Full usernames are accessible by:

  • Tapping on the truncated name to view complete text
  • Navigating to the Profile section in Settings for full display
  • Using the edit dialog which always shows the complete name
  • This truncation only affects compact display areas to maintain interface clarity

My username reverted to the previous name after updating.**​

Name reversions typically indicate:

  • Network interruption during the save process
  • Authentication token expiration requiring re-login
  • Server-side validation failure due to unsupported characters
  • Solution: Verify connectivity, log out and back in, then retry with simpler characters

Character Set & International Support

Can I use non-English characters in my username?**​

Yes, the application fully supports international character sets including:

  • Latin script variations (accented characters)
  • Cyrillic, Arabic, Chinese, Japanese, and Korean characters
  • Regional symbols and diacritical marks
  • Most Unicode character categories are supported

Do emojis count differently toward the character limit?**​

Emojis may count as multiple characters toward the 50-character limit due to Unicode encoding. Complex emojis (combinations, skin tones) may consume 2-4 characters each.

Why do some special characters cause errors?**​

Certain characters may be restricted due to:

  • System security considerations
  • Database compatibility requirements
  • Interface rendering limitations
  • Solution: Use standard punctuation and avoid system control characters

Account & Privacy Considerations

Is my username visible to other users?**​

Username visibility depends on app features and privacy settings:

  • Collaborative features may display usernames to other participants
  • Shared content may include username attribution
  • Check privacy settings to understand current visibility scope

Can I have the same username as another user?**​

Yes, usernames are display names only and multiple users can have identical names. User identification relies on unique account identifiers rather than display names.

Does changing my username affect my account security?**​

Username changes do not impact account security. Login credentials, authentication tokens, and account permissions remain unchanged when modifying display names.

Technical & Advanced Issues

Why does the app crash when I try to edit my username?**​

App crashes during username editing may indicate:

  • Insufficient device memory for dialog rendering
  • Conflicts with device keyboard or input methods
  • Corrupted app data requiring reinstallation
  • Solution: Restart device, ensure adequate storage, and update to latest app version

Can I change my username while offline?**​

Username changes require internet connectivity for immediate synchronization. Changes attempted offline will queue for processing when connectivity is restored.

Does username history get stored anywhere?**​

The application does not maintain a history of previous usernames. Each change permanently overwrites the previous name with no recovery option for historical names.

Support & Escalation

Who should I contact if username issues persist?**​

Contact support through:

  • Email: hello@notexapp.com (24/7 response within 24 hours)
  • In-app support: Settings → Contact Support (includes automatic diagnostic information)
  • Live chat: Available during business hours for urgent account issues
