I have a Galaxy Active Watch 2, for the last 2 nights, my sleep displays no record on the watch. But in the Samsung Health app, my sleep shows up correctly. Steps, heart rate, everything else seems to sync correctly, and displays correctly on the watch. It is only sleep that does not display on the watch. My phone is an S9.
I did do a reboot, but not a factory reset yet. If I do a factory reset, the apps, watch faces, etc on my phone will still sync, right? I know I would have to add widgets back, reorder, that sort of thing.
