Push Notifications Android - Firebase

Hello,  I have been attempting to make push notifications work for android using both the app store module and the github repo. In the documentation listed here: https://docs.mendix.com/howto/mobile/setting-up-google-firebase-cloud-messaging-server, under section 4.4 fields are mentioned that do not exist in the admin pages for me " The XMPP server field should have the value gcm.googleapis.comwhereas the XMPP Port field should be 5235 "  My android device is not showing up in the "Devices" tab, even though it has been configured correctly by allowing debugging, building the app with phonegap, etc.

Hi Alexander, you can easily make a mistake when configuring push notifications. You can either check the configuration again and/or debug your setup. Can you debug any error messages in the console on your device, see 4.3 Android Configuration?
