Data lost on Apple TV


my TV went to standby and that somehow killed the Apple TV app… Looks like frozen.
Unfortunately I was on PRL full at 99,9 km, last 5 hm on Box Hill 7th ascent :(.

On the activity shows up normally in the feed overview, but the zwift account does not reflect the 1400hm and the 99,9 km. I could live with the loss in zwift, but I would like to retrieve the fit file.

If I click on the activity in, NOTHING happens. simply shows a blank screen with the zwift “Z”. Any idea how to recover the data? Where does get the data from / where is it stored?

Thank you,every support welcome.
