Doorbell v2 Cameras as Chime

Wyze Camera OG is supposed to be THE flagship implementation of Camera as Chime, but…

I installed a new Doorbell v2 today where I already have three OG’s. When I try to setup “Camera as Chime” on the Doorbell, the Android app very briefly flashes a list of the three OG’s with checkboxes and then returns to the main Chime setup screen with a little popup block which just says “FAIL” with no further explanation. Unlike other users’ experiences, it doesn’t even give me a chance to even try to select cameras for chime or save settings - it fails immediately that the list opens.

All my firmware is up to date, and I am on v3.0.0 (519) of the Android app.
