We already tried to solve the issue back in january, but could not get it to work. (Trouble receiving push notifications on Android) Now we are trying to properly implement the push notifications for Android again. Sadly it still does not work.
The firebase messgaing client seems to be correctly configured, because messages sent from the Firebase dashboard are received on all devices. When specifiying a channel (eg. APPID_group_GROUPUID) and sending a message from the Firebase dashboard, all devices subscribed to the channel successfully receive the message.
Only when sending messages with Cometchat, no push notifications are received. Firebase Cloud Messaging analytics also does not show that any notification was sent. Therefore we think, that Cloud Messaging does not receive requests from the Cometchat servers. We already double checked our Firebase API key in the push notification extensions settings, but it seems to be the right one.
Is there any way to test if Cloud Messaging receives requests from Cometchat?
