I have used Anti-Theft successfully in the past, including sending commands to my lost device.
However, after I had to re-install Anti-theft on a new device due to a hardware-replacement, the device no longer received messages or commands from the server. I get a "Time Out" Message for every single command I send - also the tracking function no longer works. According to the portal, there is a connection between the device and the server though.
I use Android 4.4 and the latest Avast Anti-Theft.
Anybody else experienced this? No word from Avast support yet...
