I had this problem many years ago and simply resorted limiting groups to a max of 8 cams. I haven’t tried more than 8 per group since, but will try to recreate this issue late this afternoon. If valid (most likely), we need to post in the latest public app topic and Fix it Friday topic for Wyze visibility. I think those 2 topics are:
Wyze app 2.40 Released - 3/8/2023
The Fix it Friday topic is probably locked out by now and we may have to wait until the next iteration.
