App does not work properly on Samsung
Some customers report issues on Samsung devices. The issue is about not counting times or limits which does not take effect. First indications suggest that Samsung has introduced a "tightened" battery saving mode on some devices with ongoing updates, which may cause the Child Control's background service to stop. Please check the following points directly on the Samsung device under Settings -> Device care -> Battery -> App Power management
Adaptive battery (must be set to OFF)
Put unused apps to sleep (must be set to OFF)
