Apple TV 4K not uploading to Garmin and fit corrupted

My rides on Apple TV 4K are not saved to Garmin and the fit files are corrupted so manually uploading to Garmin Connect does not work either. I tried it both with wifi and ethernet and also forced the Zwift app to close after the ride.

please advise,

I am getting the same thing has anyone been able to help

I had  the same problem where rides weren’t saved on Zwift Activity history, and therefore not synch’d to Strava/GC.  Reinstalled the Zwift app on ATV4K has resolved the issue.
