I'm facing a really random error that I cannot debug, for the life of me. I've tried everything, so I'm really hoping someone here can help.
I've created a React native app for iOS and Android, and I'm using FCM for data messages and notifications.
Specifically, I'm using topics to send notifications.
Here's the weird part: It works sometimes and sometimes it doesn't. This is across different users and different topics. I will get a notification for a topic I've subscribed to one day and the next day, I won't get a notification sent to the same topic.
Some users will get a notification and some users don't. And they are all subscribed to the same topic.
There are no error messages. I assume this is something to do with FCM? I am at a loss on how to debug since it's so random.
Any suggestions?
