Ring doorbell 4 battery operated. The doorbell keeps going offline. I have to reconnect it and try for at least 30 mins to do it and nope it doesn’t do it. Then I’ll try a couple off hours later and it still won’t connect. But then out of the blue it will connect. It will be connected for about 5-7 days and then do the whole thing over again disconnect. I have 2 battery and always have one at 100% to put in when the door disconnects so it’s definitely not the battery. It’s driving me mad !!!! Anybody been in this situation?? Thankyou x
