My FR965 detected a nap today that was none, but me doom scrolling. So I scrolled some more to find out how to delete a nap from Garmin Connect. That worked, kind of. The nap was deleted in Garmin Connect, but the sleep coach is still recommending a reduced sleep time because of the nap. My watch still shows the nap. I synced.
Dear Garmin, reach out of you need a product manager that cares.
