After updating my Garmin Fenix 7S to firmware version 21.19 last night, I noticed an issue with the sleep tracking feature. Despite having a good night's sleep (7 hours and 10 minutes), the watch reported 0 minutes of REM sleep, which has never happened before.
This seems unusual, as the sleep tracking was working fine before the update. I’m wondering if this issue could be related to the new firmware. Has anyone else experienced similar problems with sleep tracking or REM sleep after updating to 21.19?
