Not showing logged in account after uninstall & reinstall app

[keyur-n]

I have downloaded this demo and run in devices without any changes.

If register new account & then uninstall and reinstall app again, not showing any registered account. Need to register again same user. Tried in many different devices, also in emulators etc. but same issue facing.

Is there anything need to handle this separately?

Note: Tried with both way, backup enabled & disabled.
