Huawei P9 with Android 7 not detected by account

Any ideas why avast account does not detect Huawei P9 (EVA-L19) with update to Android 7 on-board correctly? Tried everything, re-connecting, reinstalling - the result is the same. The device has Mobile Security Pro, Anti-Theft and Password installed. All apps show device is successfully connected to avast account, but account says “No detailed info available” :-\

Hi, unfortunately this error message means that the device doesn’t communicate properly with my.avast.com web portal.

To resolve this issue I would recommend to uninstall all Avast Anti-Theft together with all other Avast applications, remove the device from my.avast.com account and then download Avast Anti-Theft again and try to connect it to your account once more.

If this doesn’t help, then I can only suggest to backup all you important data and hard reset the device and then download Avast Anti-Theft app again.

Seems it solved a problem - at least account detects the device now. Yet, at this moment account shows no Anti-Theft installed, but maybe it will detect it a bit later.
