This has been the second night in a row that my sleep data hasn't been tracked. I know the green light on the underside is still working. I wore my watch a little tighter just to see if it was too loose to track hear rate for it. I made sure it was fully charged. But syncing with the app yields nothing.
As an additional test I've made sure the app was up to date, and I logged 1 oz of water both days and resynched. App recognized that I'd logged the water and recorded it, but no sleep data.
