Just looking for some help with my Ring 2 doorbell. The doorbell is fully charged, has good WiFi signal but stops working after an hour or so. The doorbell doesn’t make a sound on the unit or even give a blue light when pressed. If I detach it and plug it in it seems to “wake up” but again goes off after an hour or so. I have tried deleting the device and re-installing, changing the WiFi network etc but to no avail. For the life of me I can’t work out whats going on! Any help would be much appreciated. The unit is only about 2 months old.
