Rapid Ring app being phased out

I have a Ring Pro doorbell camera along with the indoor compact camera. I was using the Rapid Ring app until my Doorbell Pro wouldn't connect to it. My indoor camera still did. Also, both cameras still connected to the main Ring app. After uninstalling the Rapid Ring app & installing again, the problem persisted. I called support twice. Both times I was told that Ring is phasing out the Rapid app and it is no longer supported. I found older versions of the Rapid app and they had the same issue. The only conclusion is that Ring is updating the Doorbell cameras firmware and blocking the Rapid Ring app. Otherwise, the older versions would still work.
