I started my scheduled Trainer Road workout from the Next Up card and within a couple minutes had to stop and restart. I exited the workout and discarded the ride (ie I did not save). When I went to restart, the Trainer Road workout was no longer listed in the For You or Next Up recommendations. Prior to the beta, if you cancelled out of a TR workout and then went to restart, the workout remained in the For You section. I tried a couple different things to try to get TR and Zwift back in sync but was not successful.
