Thanks for all the replies. I’m going to try to remove the entire Cam Plus Lite plan from my account and re-add it to see if it works.
But for the record here are some screenshots of the problem:
As you can see, there isn’t even an “add cameras” button on Android. This support article clearly says there should be such a button: https://support.wyze.com/hc/en-us/articles/4694216804251-How-do-I-assign-Cam-Plus-Lite-to-my-camera-
There is also a thread from March I found, that talks about the missing “add camera” button that was supposed to be fixed??? Obviously it’s not fixed, or did they reintroduce the same bug a few months later? How to turn on Cam Plus Lite - #44 by rhousen
There is also a thread about the forced Cam Plus trial all the way from 2020. But I see Wyze doesn’t really care. CAM Plus Trial forced signup
Edit: just found support article regarding changing Recording Type to Video https://support.wyze.com/hc/en-us/articles/4689998868507
But the option is literally not there as you can clearly see from my screenshots.
