Numerous existing Forum topics discuss the issue of microSD recording/recognition/playback ceasing to work on some Cam Pan v3s, though I’ve never seen a complete, definitive, and reliable explanation for why this would be. If you’re still trying to use Wyze app v3.2.6.592 for Android with a Cam Pan v3 running firmware version 4.50.15.5336, then that’s not going to work very well. (Maybe that’s not what you’re doing; I didn’t see a firmware version mentioned in your post. 
)
A new one was released just yesterday, so that complicates the picture. 
I’m still stumped by this issue, too, and I’d like to see an official answer of what causes it along with a fix, particularly since one of my Cam Pan v3s has been afflicted but the other has not. It’s really vexing.
