• Topics on Firebase Cloud Messaging? 2 answers

I am developing an Android app that uses Firebase Cloud Messaging. For the back-end, I am using ASP.NET MVC.

I am using Topics Messaging to push notifications to multiple devices. I will create topics dynamically.

Please see my scenario: I dynamically create a topic from admin panel. Then users will subscribe to that topic at the client side (Android). I will push the notifications to the subscribed users of that topics, but my application may have thousands of topics.

My question is, is there any limitation for the number of topics for Topic Messaging in FCM? It may work during development with few numbers of topics, but I am worried that maybe it may hit a number of topics limitation when my application goes live.
