@Tim_Lin and @Jen_Wrench If you are running Zwift on AppleTV login then at the bottom left after the pairing screen is a “restore purchases” link. Click that.
This happens when there is an issue between Apple communicating your active subscription to Zwift. No need to contact support it’s an easy fix. Only happened 1 time to me when I was using AppleTV and never happened since I cancelled iTunes subscription and now pay through Zwift’s website.
