Custom workouts not syncing across devices (iPad --> AppleTV)

Hi there,

About 4 weeks ago I noted that the custom workouts I create on my iPad are no longer syncing to my AppleTV. Despite the recent update this is still occurring.

I can, however, edit custom workouts that were previously synced across both devices and these edited versions appear to update on my AppleTV.

I have deleted and reinstalled the Zwift app on both devices and this does not seem to have fixed the issue.

Previous posts in regards to this suggest tinkering with workout data files etc but on both iPad/AppleTV this is not possible.

Does anyone else have this issue?
