Setup will not Complete on iPhone Ring App

Hello All: I just purchased a Ring 2nd Generation doorbell and almost everything is working well. I have it hardwired to my pre-existing doorbell and connected to my pre-existing mechanical chime. When the button on the Ring doorbell is pressed, the indoor mechanical chime sounds, I get alerts on my iPhone, I can speak to and hear the person outside who rang the bell, the app records the activity, so as I mentioned, just about everything is working. The issue I'm having is the in-app setup doesn't successfully complete (even though everything is working). It fails every time at the "Chime Connection" step, even though that's working. When I press this step, the app says "Checking your doorbell system...We're making sure your Ring Doorbell can receive the power it needs", then the message displayed reads "Something went wrong." The app says Setup Incomplete and I always see the message at the bottom of the app that says "Tap here to complete your device setup". I've read numerous posts that point to the doorbell transformer as possibly being the culprit for similar issues, but as I mentioned, everything works, the chime, the audio, the video, etc. So my question is has anyone experienced similar behavior and could the transformer be the issue even though it seems like the doorbell is receiving enough power to perform all the functions?
