I need some advise on firebase messaging?

Q1. How to enable lines to have a new line?

Q2. What is the best approach to subscribe and un-subscribe from topic during runtime, like I want to be able to turn these on / off? The topic names change depending on whats on the db?

Thanks

A1.

B4X:

Send("general", "title", $"First line
Second line"$)

A2. Not sure what you are asking. You should call fm.SubscribeToTopic or fm.UnsubscribeFromTopic.

Thank you, On Q2, I only thought the

B4X:

CallSubDelayed2(FirebaseMessaging, "SubscribeToTopic", "topicx")

was to be done only on the starter service, I've called it from B4XMainPage, its working.

For Q1, I'll try your code, as I need to show a Notification with new lines, at least 4 lines.
