We are unable to connect to your device

[REDACTED]

[opening up a new thread as other ones appear to be either stale or mix several symptons]

I have 3 mobile devices in my Avast account (all running free version of Avast mobile security).
For tho of them all is fine.

However for one recently added phone (Lenovo P2 with Android 7.0) I receive a "We are unable to connect to your device" message for any command I try (Locate, Siren, Lock...).
This message is appearing immediately on pressing send/locate, NOT after a timeout.
Info->Command shows: "The command could not have been delivered"
Info->System/SecurityInfo/Anti-Theft/etc looks OK.

I tried to reinstall,  reconnect to account (even to a different account) without success...

Any idea causes this immediate rejection of communication and how I can fix it?

Thanks, Stefan

AT is not free anymore.
For everything to work you will need to get AMS Pro.

the basic AT functionality is still free.
...and also comms works just fine for my other devices...

Hi, the original, standalone Anti-Theft should still work, but is not supported or developed any more. Since the inclusion of Anti-Theft to the Avast Mobile Security Pro, we have not been able to guarantee that standalone Anti-Theft will work flawlessly, and also all security fixes and new features will happen just in the Avast Mobile Security version.

to clarify: I'm using the new integrated (in Mobile security) version.
It offers locate, siren and lock as free....
Works fine with 2 of my devices, jut not on the 3rd one...
