Apps going to sleep even turned of Xiaomi Battery safer for that app. Any Idea? I did "Autostart" and turned off Xiaomi Battery safer in App Settings, but my apps go to "sleep" somehow, whatsapp for example does load new messages only after opening the app.

Did you solve this problem? My texting app on a mi note 10 lie keeps going to sleep.
