Just for clarification, you’re saying that Zwift eventually sorted this out by itself and now you have access to the desired workouts, correct? Or am I misunderstanding you?
Within the last month or two, there have been some significant changes to how the Training Plans function and it’s still a work in progress; I believe more changes are expected to come in future Zwift updates.
That being said, if you’re enrolling in a training plan but don’t have access to the desired workouts, we recommend that you locate the training plan (e.g., Build Me Up) in the standard Training (Workout) menu, and you should be able to find all the workouts there in the prescribed order.
