Mobile App no longer ringing

[cleanden]

I have been cautiously deploying and testing my 3CX server. Today I set up my first desk phone and since that time my Android App never rings.
When I am calling my extension, the mobile app shows my Status as yellow so it recognizes the call but doesn't seem to be associating itself with my extension, and nothing shows in Recents.
The Windows app and the Web Client both seem to be working fine, they ring when I call my numbers.

I tried removing my account from the app then re-scanning the QR code to re-add it but it made no difference.
I closed out the Web Client and the Windows App, then I disconnected my desk phone and when I call it now I can hear the call ringing in from the calling phone, but my mobile app sits silent.
I also removed and reinstalled the app with no change.
Enable PUSH for smartphones is enabled

Please ensure you have the latest version of Android and of 3CX... Update 8 is required

Thanks Nick,

3CX shows v16.0.9 and no updates available, and my phone is Android 10

Sorry, here you go:

Phone Model: Samsung Galaxy S9
Android Version: 10
App Version: 16.6.2
3CX PBX Version: 16.0.9 on Ubuntu
Network Connection: WiFi and LTE / IPv4
Client is on the same network as the PBX or not? Not. 3CX is cloud-hosted


Trying to open the FCM Diagnostics app, but when I dial *#*#426#*#* I am told the called can't be completed as dialed. When I dial *#*#8255#*#*the number disappears from screen as I complete the sequence

Could you please try creating a brand new extension in the Management Console, scanning that extension from your Mobile and then try calling this new extension from another extension?
Does the same happen?

You may also want to try disabling IPv6 on your 3CX server as that can sometimes cause PUSH issues.

I just created a new extension, and before I even had a chance to test it I got one of the Welcome Emails I had requested, and my app now shows all kinds of info in Recents.

This is just plain weird.
