My sleep tracking seems to have stopped happening. I know I'm sleeping, my watch doesn't seem to know it. I reset to factory defaults again (had to do that for stress too a few weeks ago but that still seems suspect). I like tracking my sleep. :(
Strangely enough mine didn't record sleep or stress for last night. Only difference was I decided to try transfer via wifi this morning, which failed. HR is working correctly. Its almost like the failed wifi attempt wiped the data.
