Yes, take a look at the Apple Watch posts in this subforum. There are a number of issues. It got worse since the last update. Zwift isn’t really supporting Apple Watch functionality. FYI, if it continues to run like it did, reboot the watch. If it continues to run after you reboot (like mine did this weekend), start another activity using Apple’s native activity app (ie, start an outdoor walk). Then end it. The little running man should stop. Then reboot your watch again. It’s a joke that they can’t get this working.
