Constant Doorbell Rings

Hi...I have a number of Ring doorbells around my home. Early this morning, one of them started to repeatedly ring. These are NOT motion-sensor alerts...it's as if someone was actively pushing the button. This particular Ring device is not connected to any power source...it's in a location which is covered and protected from the elements. I recharge it regularly and the battery currently stands at 54%Even when I bring the unit into the house and set it on the countertop, it repeatedly rings...every three minutes or so.Every 30 seconds or so, I hear an audible click coming from the device.Any thoughts?
