I updated Anti Theft today, installed rooted. I’ve reset the device, uninstalled, re-installed various times, saw my cutom app name in the app tray, which disappeared upon enabling anti-theft due to stealth mode. But when I log into my acount on the avast site, it states that anti-theft is not installed and I cannot remotely control / access my phone.
The notifications tab on the site shows that I’ve repeatedly enabled / disabled anti theft, so the site is aware of the program on my phone, but for some reason I cannot use the controls, even though the last notification shows that anti theft was enabled.
I think your issues can be related to a bug present in previous AMS/AT version where at some points in time the package settings of AMS and AT possibly got out of sync. You can solve your problems simply by upgrading AMS and AT (both of them!) and unpairing and repairing your device.
