What to do if I cannot log in or sync app data on the Mi TV P1 55

If you're experiencing trouble logging in or syncing app data on your Mi TV P1 55, for your reference, here are some troubleshooting steps you can refer to:
1. Check Internet Connection: Ensure that your Xiaomi TV is properly connected to the internet. Weak or unstable internet connectivity can hinder login and syncing processes.
2. Restart the TV: Turn off your Xiaomi TV, unplug it for a few minutes, and then plug it back in. Turn it on and check if the login and syncing work.
3. Check Google Account Credentials: Ensure you're using the correct Google account credentials to log in. Verify that your account information is accurate.
4. Update the System: Ensure that your TV's firmware and the apps you're having trouble with are up-to-date. Go to [Settings] >> Select [Device Preferences] >> Select [About] >> Select [System update] >> check for update.
5. Clear App Data and Cache: For the specific apps causing trouble, you can clear their data and cache. To do this, please go to [Settings] >> [Apps] >> select the app >> [Clear Data] and [Clear Cache].
6. Factory Reset (last resort): If all other methods fail, please reset your TV to the factory defaults. Go to [Settings] >> select [Device Preferences] >> select [Reset] option >> select [Reset].
We hope the above methods can resolve the issue. If the issue still persists, you could submit your feedback on your TV by going to [Settings] >> [Device Preferences] >> [Home screen] >> [Send feedback].
