My sleep chart is not showing my sleep history from last night.
Try turning on sleep mode and then go back to your charts and select day, week e.t.c
I just got my replacement tracker in the mail and the sleep mode still isn't syncing with the app. The distance is now showing up on the app, which it wasn't before, but not the sleep. I've already tried all the things they say to try, and at this point I really think it's the app and not the tracker. They need to do an update to fix this. The sleep mode used to work fine for months, but then it just stopped syncing.
