APP background battery usage setting changes by itself after last update.

[Deemer]

The background battery usage setting on all my apps automatically switches to off after the last update.  When I turn it back on, after 5 days it switches itself back to off.  Very annoying to be listening to music then have the music stop because the app turned off by itself after it changed the background battery usage setting to off by itself.  I have a car key on my phone, but I still can't use it because everything I go to unlock my car the app is off even though I keep leaving the seeing to on.  This phone keeps changing the battery setting on is own.  How do I change the background battery setting and keep the seeing I select without the phone automatically changing it every 5 days???

 I keep selecting the "on" setting, but a couple of days later it automatically switches to off.  It happens mostly on the Amazon music app where it switches to off after every use.  The Tesla app switches to off after 3-5 days.  I haven't noticed with other apps.
