I haven’t experienced this, but my first inclination would be to reboot the camera. What I have seen when playing with the 1-minute video files is that I’ve had to change the audio encoding in order to concatenate the files into a longer video, and, while I don’t think that’s the issue here, I bring it up to say that the combination of audio and video codecs that Wyze is using might be a little odd and cause some unexpected problems.
What happens after you reboot and attempt to replicate the issue?
