Hi,
the FCM works pretty good. But there is one little problem, I can't get rid of:
When a user opens my app including the FCM features for the very first time, the string variable token_id contains no value:
However, when the users closes the app completely so it's longer in the background and starts it again, then the variable token_id contains the token string.
When the user deinstalls the app, this starts all over again, i. e. the first time, you start the app, no token is stored in token_id, you must start it a second time. From that I conclude, it's not problem of Firebase.

B4X:
token_id = fm.Token
