I had problems with the sleep data sync as well, after the update on Friday. Today’s update fixed this issue. But while I tried to help myself with the connecting problem, I followed the instructions to disconnect my watch from my phone and app and reconnected it afterwards. Since that my alarms on my app were gone while the settings on my watch remained. When I now try to set a new alarm in the app, it does not show on my watch. Additionally I can not remove the alarm settings on my watch, I can only activate or deactivate them. Hoping for a solving update here too. Thanks!
