Why does my Apple Watch not tracking sleep sometimes?
Everything is set up perfectly on both my Apple watch series 9 and my iPhone 13. Sleep is tracked most nights but periodically, even though the watch is fully charged, and securely on my wrist and all settings are the same, it does not track the sleep. I never had this problem with Fitbit. Sleep focus in on, Sleep tracking is on etc. as per all of the instructions given previously. Is this an Apple watch problem? do others experience this? any solutions?
