I have upgraded an app from v3 to v5 backend.
Users who have never been logged in the past seem to be exempt, but I think users who have used the old app in the past which was running on the backendless 3 and now who download the new app running on version 5 backendless are having trouble when they sign in.
I ‘think’ the problem is to do with user tokens, we are getting this error in testing: Not existing user token - Relogin user to update your user token
How should we handle this. They can’t logout and relogin because the app already thinks they are logged in so doesn’t show this option.
Is there anything you can think of to solve this without changing any code or requiring an app update. New users who have never used the app in the past seem to be unaffected.
