Hi, I get into trouble…
I created app and released app.Then trouble havd happened.
Users signed up and user my app. Next, they closed my app, and restart it.
This moment, this users don’t sign in but they can watch the screen they can’t watch if they sign in.
Because of this, the data of user’s signed in don’t insert Name and Email into a collection like this picture.
Please teach me how to maintain user’s signing in or other resolution.
