I have an app with Firebase authentication.
Some of my clients reported that they have to log back into the app when they just get out of the app, let it run in the background, and come back.
It appears that this issue occurs with Iphone users, but I tried on the same iphone and I have no issues. Seems like it occurs to some users.
I have no issues at all with android, as I can shut off the app completely, come back days after, and still be logged in!
Any idea why?
What would be a fix?
I have the function Initialize firebase on the global canvas.
I have a login page with the default functions of firebase.
And the Set auth state persistence (Firebase Auth) is on local, so that it should persist upon closing the app.
