Problem with Sleep Tracking on FR 35

I wore my watch during the night last night, but my account on Garmin Connect after syncing says there is "No Data". It worked a week ago... does it take until tomorrow to show the sleep data from last night? Is there something else to check?

I had the same problem and found the solution on this forum:

Your Privacy Settings do not allow sending data to the Garmin Account (verify the option Storage & Processing), or the device is not set as the Preferred Activity Tracker (check out the Device Settings on the Garmin Connect Mobile app » Activity Tracking » Preferred Activity Tracker)

Like most smartwatches and fitness tracking brands, Garmin tracks sleep time and quality throughout the night. Although its system was pretty simplistic before 2018, the company has since built more features into its sleep tracking product. Now called Advanced Sleep Monitoring, the system tracks a slew of metrics to help you monitor and improve your sleep. Below is everything you need to know about Garmin’s sleep tracking tech.
