I have ZoiPer Premium on Android, latest version (2.9.19) and I am trying to turn on Active Wakelock, but am unable to access the Background Mode setting under Settings > Connectivity, as it's grayed out and unlickable. I have all permissions granted to ZoiPer, including excluding it from any battery management/optimization, and I have also made sure Run In The Background is checked and active. Anything else I can or alter on my Note 5 to try and get Active Wakelock turned on? Thank you!
