I’m starting a new thread because Ring chose to mark the last in-depth discussion as Solved when this problem IS NOT SOLVED!
They forced a new firmware to these devices which stop them from charging unless you live in the tropics. Spend countless hours troubleshooting, spending more money upgrading the transformer, wiring, all which did not solve the problem. Ring now states their product will not charge in the cold and they have disabled charging to the device. Guess what? That hardwire doesn’t actually power the doorbell, it CHARGES THE BATTERY THAT CANT CHARGE BECAUSE THEY DISABLED IT.
Get your sh*t together Ring! We have already pinpointed it to when your firmware was released that caused the issue, and you have not once acknowledged a problem or tried to be of assistance.
