AVG management console doesn't see Android devices

I have AVG Ultimate installed on 2 Windows 10 machines and I have Android tablet as well as 2 Android phones that also have AVG installed. They were all visible in AVG management console, but then I removed 2 phones. I tried to add them back through device settings on console. An email invite was sent, I re-logged to AVG my account several times on both phones, still they are not visible in the console.

All 3 Android devices are successfully logged on to the same AVG My account. Also, all Android devices have anti-theft turned on and all 3 are visible in my.avg.com with correct information.

Hello Mario,

I understand the inconvenience.
The reason for this issue is because "ZEN" application is no longer available for AVG in Android.
We have already passed this to developers team and they are working to find a new solution but this process will take time.
Your patience is much appreciated and right now it is not possible to manage Android devices from AVG user interface installed on your PC.
Feel free to contact us if you need further assistance.
