Ring Gen 3 Video Doorbell and Chimes

I purchased the Gen3 Video Doorbell a while ago. To date, I have never gotten a wireless chime to work. I don't have access to an iOS device, only Android. What chimes are compatible with the Gen3 Video Doorbell or is there still a problem inside the Android Ring App that prevents establishing connection? I have tried to connect to the existing wired doorbell/chime transformer in the house...but apparently it is too old to function with Ring...and it will cost me way more to update/upgrade the existing hardwire setup.
