80 - fantastic! You are in inspiration. The Training Peak purchase of Indie Velo is MASSIVE! I see so many Zwifters of old on there now (on Strava).
I think it had something to do with an iOS updates. At least it looked that way when I had some.
On a Macbook Pro M2 Max iOS 15.0.1 and iPhone 15 with iOS 18.1. Re-installed Zwift on my Macbook and during it asked permission to share with other devices/apps (on local network), said yes. Since then it is working like a charm.
I think the updates reseted the setting. Something I will keep in mind with future updates.
