I have a Ring Mailbox alert and army Bridge. The sensor stopped working while I was out of the country for several months. When I returned I replaced the batteries but it could not find my Ring Bridge. I checked it and it seemed to be functioning with the blue light solid. But Rng App said it was offline. I tried to reinstall but after scanning the QR code it said “RING BRIDGE IS PREPARING ITSELF FOR USE”. AFTER AN HOUR I CANCELLED. Now when I try adding the Bridge it tells me that it is already installed (but it does not show as a device) and that I need to go to Device Settings and General settings to remove it. But the only thing in Device Settings are my Three Ring Doorbell Cams. HOW DO I REMOVE A D REINSTALL THE BRIDGE SO THAT I CAN USE MY MAILBOX SENSOR??
