Welcome to the Forum, @kenfink2! 
You seem to have done good troubleshooting steps. Unfortunately, this feature seems to be kinda iffy for a lot of users. I’ve been able to use it at will with my own Cam OG, but my current issue is that I can’t turn it off for one of my Cam Pan v3s. :shrug:
I wonder about two things:
- I don’t know if you’re attempting this with the new v3.0 app or with v2.5x. Google Play Store hasn’t yet offered me the new app version, so I don’t have any personal experience with it.
- I wonder if any of the difference in our experiences can be attributable to Video Doorbell v2 firmware differences. I’m still using the Doorbell firmware update from January because of the issues with notifications that have been reported with newer versions. I don’t know if any of that has a direct effect on the “Cameras as Chime” feature.
I’ve noted in other topics[1][2] that Wyze (within the past few weeks) changed its message in the “Can I use a Wyze Cam as a chime for Wyze Video Doorbell v2?” Help Center article, which I interpret as their recognition that the feature has some bugs that need to be worked out before it’s expanded to other camera models, but that’s just speculation on my part.
If you have them available, then other things can be used like accessory doorbell chimes, like Google Home smart speakers or Amazon Echo devices, but I don’t have experience with doing it through Alexa (and I’ve read that this can be hit-or-miss), and using something like a Google Home Mini (which I use for doorbell button press announcements) requires a work-around.
