I am subscribing to events from FCM Android client and removing from server side code when something happens in the backend database. So based on this I have ome around a situation where if i subscribe to event event123 and than based on some factors from InstanceId API I call batchRemove call from my node backend to remove that person to stop receiving pushes about that id. Then I again client can re-join the event from Android device. But this does not work.
I also tried to call the API from the REST client but I am unable to add the person to that event group. I get 200 OK, but still I am unable to join the group. When I query the instance id, It doesn't give me the event I tried to re-subscribe.
What's the issue? Am I missing something? Or no instance id can rejoin a topic?
UPDATE: I have contacted the firebase support for this and this is a bug at the moment. I am not sure if it has been released or not, as I have not been updated with the release status.
