US Axon 7 5.5" running 7.1.1. I have set all the power management settings to keep my TinyCam app awake but it still goes to sleep. I use this app to monitor 2 baby cams (overnight) on my wifi. No matter what I try to configure I still wake up in the morning to the app not working. It is supposed to alert me to motion with an alarm sound and system notification. The app works well for a few hours with the screen off but some random time, overnight, it goes into a "deep sleep" and will not sound any alerts. If I wake the screen up it works so I have no clue to the reason it goes to sleep. I have tried a different app with the exact results. I have checked all Do Not Disturb and Power Management settings to make sure it stays awake, even the permissions are all granted. There should be no reason that it sleeps but it does! Any clues on how to troubleshoot this or even fix it? Thanks ahead of time for any help.
