I would love to be able to stop images from uploading to Strava when using the Apple TV app. On the save screen, before exiting, it says you can de-select the image by pressing the remote, but that doesn’t seem to do anything.
I have the same problem. Quite annoying!
If you want no images from Zwift to be uploaded to Strava then you can turn this off from within Strava.
In Strava phone app, go to Settings and find Partner Integrations option. Here you can turn off Zwift integration and auto-uploaded images from Zwift won’t show anymore.
