Im having issues restoring the pro version on Android tv.
Toast message comes up
"Button Mapper Needs To Be Restarted"
Force stopped, un installed, rebooted the box but it's not activating the pro functions.
It works just the same as always, the problem is Samsung killing the service. That is something beyond my control. Check dontkillmyapp.com
Uninstall and reinstall. I can't think of any reason why the volume button settings would be disabled unless you are using an extremely old setting called "Bixby only". That setting was only meant for the earliest generation of Bixby phones, before Samsung started their war on remapping apps.
