In cases where the watch is fired up from the phone, the status bar may hang over the screen. To fix, end the activity and force “close” the watch application by holding the power button and then holding in the crown. We hope an updated watchOS version will fix this issue in the future.
Then “open” the watch app, or start the workout from the watch next time before firing up workout from your iPhone.
We know other apps seem to have just avoided the phone > watch API because of above bug, but it is too useful for situations where use cases rely more on the iPhone than watch.
