Hello  
In first screen user can sign in with firebase and his user ID is saved in a stored variable. Then moves to 2. screen.  
In there the user can save some date in Firebase, with his user ID as reference.  
However, after the call save to firebase the variables used in the key get value null.

Is anyone else having the same issue?

(Downloaded App & Live test, latest IOS)

Are you saying the user data become null after saving. It disappears?

Or the variable does not save the value after using it once?

Can you post block screenshots?
