Which Garmin device do you have?
This is happening to me. Garmin 245. No sleep, respiratory or heart rate data for over a week. Anyone help or advise what to do?

The device came out about 4 years ago. So there is no specific forum related to it. Nonetheless, I'm moving this thread to the vivosmart 4 forum to see if we can get more visibility regarding your issue.
