Missing Workouts for iOS 15+

[piscoTech]

It's been reported that workouts recorded on Apple Watch without connectivity with the iPhone will not show up in the app, although available on the phone (inside Fitness/Health?)

for some reason, i can now get data on Apple Workouts (heart rate / location), but it doesn't transfer for some exercises. for example, when i ride, the data comes over fine. when i run (watch only, no phone), the data shows up on the phone when it syncs. but there is no data in your app. again, only since newer IOS updates on phone & watch.
