I have an s21 ultra running the same app version and I’m not seeing any of this behavior. I thought it might be because the hardware decoder was turned off but in doing that I was unable to replicate it. I don’t know what might be causing that issue other than maybe you have too many other apps up and it’s actually overloading the system and your operating system is shutting down the newest app to preserve everything else. But that’s pure speculation I haven’t run into that yet myself. I can’t find anything in the wyze app that would cause this
