I have 3 Android devices running AMS 5.0.17, and 3 Win 7 Pro SP1 laptops running AIS 2016.11.1.2253. On my.avast.com all but the Toshiba laptop are updating their VPS status, etc. This Toshiba stopped doing so around February 18th, and a repair of the AIS installation did not fully correct the issue, updating the my.avast.com status only once on the first Windows restart after repair. However, with the Toshiba on, the other laptops can see that it is online via my.avast.com so there is some communication.
All devices, of course, are linked to the same my.avast.com account.
