On Android 11 Samsung will prevent apps work in background by default unless you exclude apps from battery optimizations. This is a severe divergence from standard Android process management policies. To keep your apps working properly make sure you enable:

  • Settings > Apps > TimelyBills > Turn off Remove permissions if app is unused
  • Settings > Apps > TimelyBills > Battery > Battery optimization > All apps > TimelyBills > Don’t optimize
  • Settings > Battery and device care > Battery > More Battery settings > Turn off Adaptive Battery 
  • Settings > Battery and device care > Battery > More Battery settings > Turn off Protect battery
  • Settings > Battery and device care > Battery > Background usage limits> Turn off Put unused apps to sleep
  • Settings > Battery and device care > Battery > More Battery settings > Turn off Protect battery
  • Settings > Battery and device care > (⁝) menu > Automation > Turn off Auto optimise daily
  • Settings > Battery and device care > (⁝) menu > Automation > Turn off Auto restart at set times
  • Settings > Battery and device care > (⁝) menu > Automation > Turn off Adaptive power saving
