Fixed! I have the doorbell 2. It was working my interior doorbell for a long time then all of suddent stopped. I have no options in my app to enable mechanical doorbell - just like many others have mentioned. I called support and spent of lot time troubleshooting with them but never got a resolution. I read another person’s note on here about the part connecting being too short. I also read online that if your app is telling the doorbell is getting its charge from the battery it’s not connecting to the wiring. Long story short, I took off the back of the ring door bell and added 6-8 layers of foil (I folded the foil over) and now the indoor chime is working again! I’ve attached a picture. There are two gold nodes. I covered both with their own foil. In this picture I left one gold node exposed so you can see what it looks like.
