Can you set your normal sleep hours also directly on the watch or only in Garmin Connect?
Set it in connect for normal sleep hours but the watch senses if you go to sleep a little early and adjusts accordingly. If you wake up early go to your sleep widget and shut sleep off, then it'll sync with your connect app.
How to change sleep hours target
In Garmin Connect app,
Device (Fenix 6) > User Settings> Normal Bed Time.
