I have been experiencing for a while this issue. If somebody is ringing my Ring Doorbell Pro it will shut down and it will be disconnected until I turnoff/turnon the breaker and it will reboot.
I verified the wiring connection and it seems fine. the doorbell is also connected to a mechanical doorbell inside the house.
Now last night, I set the internal doorbell settings from mechanical to none and it seems to no longer happening.
Do you think the issue is coming from the mechanical doorbell itself causing the ring to shutdown everytime is pressing the button or is it an issue with the transformer ?
The voltage right now for the device is 3914 mv.
