Troubleshooting

Steps to diagnose common problems such as the app not starting, sync not working, or being unable to log in.

The App Won't Start

Desktop

  1. Quit once and restart
  2. End any leftover processes in Activity Monitor / Task Manager, then restart
  3. Reinstall the app (your data is retained)
  4. If it still does not resolve: send the logs from ~/Library/Application Support/niyase/logs (macOS) or %APPDATA%\niyase\logs (Windows) to support@niyase.com

Mobile

  1. Fully quit the app and restart
  2. Update the OS to the latest version
  3. Reinstall the app (caution: local data will be erased, so back it up first)

Can't Log In

SymptomWhat to do
Password not acceptedSend a password reset email
Email not arrivingCheck your spam folder; allow the domain @niyase.com
Two-factor code not acceptedCheck your device's clock sync / use a backup code
Passkey not respondingCheck your OS biometric settings / log in with another method, then re-register the passkey

I Can't Find a Menu or Screen

Since the July 2026 redesign, the top horizontal app bar has been replaced with a rail-style sidebar (cloud / desktop) or a shelf (mobile). If you can't find a screen, type its name into the command palette (⌘K / the search icon) to open it directly. See How navigation works for details.

Sync Isn't Working

Sync is designed to self-heal so it rarely gets stuck. Local tables left behind after a plugin is disabled are automatically dropped and reconciled, and sync runs are always processed one at a time in sequence, so duplicate or stuck runs are much less likely. If sync still isn't working, check the following:

  1. Click the sync indicator at the bottom of the rail (or in the header on mobile) to view details
  2. Check your network connection
  3. Space settings → Sync → "Retry sync"
  4. Check whether the relevant space's plan has changed to FREE (FREE cannot sync)
  5. If it still does not resolve, check the error records in the audit log screen and send them to support

Notifications Aren't Arriving

  1. Check whether the relevant category is turned off in your notification settings
  2. For push notifications, check your OS-level notification permission settings
  3. For email notifications, check your spam folder and allow the domain @niyase.com
  4. Notification content is rendered in each recipient's own language setting, so the same notification may appear in a different language for different members (this is by design)

See Notifications for details.

My Data Disappeared

  • First, don't panic — open the same space on another device to check (if cloud sync is ON)
  • You can identify deleted records from the audit log
  • The local DB may be recoverable, so stop the app and contact support@niyase.com (do not perform any operation that overwrites the DB)

Printing / PDF Looks Broken

  • PDF: Update to the latest version, then regenerate
  • Printing: Check with the preview function → instead of browser printing, we recommend the in-app "Save as PDF → Print"
