Ring (2nd Gen) Worked Before Install, but not after

Got a Ring (2nd Generation) for Christmas. Before installing, I downloaded the app for my android phone and for my Windows 10 computer. I followed all the directions for charging the bell, and setting up with my WiFi. Everything worked fine. Ring would notify me by phone and by PC every time someone walked by my computer desk, and the live view and mic/speakers all worked fine. As I was installing today, replacing my existing doorbell, I cut the breaker to the doorbell, removed the doorbell, and connected the two wires to my Ring. As I connected the 2nd wire, suddenly my Ring announced that it was in setup mode. I finished installation, but then could not get Ring and my phone to communicate. The Ring circle of light was white and spinning. However, my phone told me the device was healthy and all was well, connected, and congrats! I then opened the app on my computer, tapped "Live," and got a short message "activating." About 5 seconds later, live view worked. However, ringing the bell did not ring my existing bells in my house (mechanical, not electronic chimes) and I could not hear my wife when she spoke (should could hear me through the Ring, though. I went back to my phone, and live was working, but with the same issues. No bell, no voice. What's my next step? My Ring came with a separate chime to plug in to a wall outlet. If I use that, do I also disconnect the original doorbell wires from Ring? I really didn't want to have to do the wireless if possible, 'cause I know me, and I'll forget to get around to charging the thing. :slight_smile:Thanks for any advice you have for me!
