Ring Doorbell Autorisation button not working

If people would like to see the app come back maybe you can send a new feature request to Athom https://docs.google.com/forms/d/e/1FAIpQLSc8j_GfID4adV4w5ogNtIX1-AqVWrkgIo3bOjkoNtqlHMM0xw/viewform.

Athom stand a better chance of becoming a partner with Ring than a single individual.
If they get enough request perhaps they will consider it.
