Charge 3 can’t set up Airlink.AirlinkRequestError

[SunsetRunner]

charge 3 acted up last week - display started randomly flashing, vibrating, etc. Reset numerous times. No change. Finally left hooked up to charger for a couple  days - then seemed to work. Today, time is out by 3+ hours. Kept getting sync errors. Tried numerous resets, sync attempts. None worked. Deleted device from account. Deleted app on iPhone. Downloaded new app. Tried to add new device - it gets to pairing then after adding the code, I get an “Airlink.AirlinkRequestError error 0” message & continual pairing codes. Seems to be stuck in a loop. None work. Have turned phone, charge3, Bluetooth on & off numerous times - same result. Tried setting up in a different iPhone - same thing. Help? TIA.
