Troubleshooting and support
Start with the checks that do not change your data. Do not delete the app or your account as a first step.
General checks
- Check your internet connection if you use Pro or an online calendar.
- Close the affected view and open it again.
- Check the app version and account status under Settings.
- Install available updates.
- Create a backup or export before larger changes.
Sync between devices
Check that both devices are signed in to the same account and that Pro is active. Start another sync from Settings. Do not continue editing the same entry on both devices while a conflict notice is open.
Notifications
Check the system permission, app switch and reminder time on the specific entry. Send a test notification on the mobile device. Detailed steps are available under Notifications.
Calendars
Check the calendar permission, selected read sources, export target and time zone. Google requires Pro. Outlook has not been released yet. See Connect calendars for details.
Apple Watch or widgets
Open the iPhone app first and then the Watch app. If a widget is out of date, open the iPhone app, wait for the daily view and return to the Home Screen.
Contact support
Email support@meinsystem.app. Helpful details include:
- a short description of the expected and actual behavior
- device, operating system and app version
- the affected area
- a screenshot without data you do not want to share
Under Settings → Report a bug, the mobile app can prepare an email with technical device information. Keep the debug information if you are comfortable sharing it.
