If you have more than one Wyze device, it might be related to issues in this thread.
I have three cameras registered in the Wyze app, The camera in position 1 in the app is seldom used. Cameras in positions 2 and 3 are active.
In TinyCam, I have to set the two active cameras to channels 2 and 3, because the info that I have three cameras and 1 inactive is stored somewhere outside the Wyze app and is communicated to TinyCam when it runs.
