Help! I can't for the life of me get any of the available custom workouts from the Zwift library to load onto my custom workouts!

I’ve been able to do this with easy many times in the past, but now I’ve been trying for a week to load the Akitvitus 14 week power and endurance workouts from the "whats on zwift’ library with no luck. I’ve tried every recommendation on the general help pages. I’ve emailed support but got no reply yet. Looking for any help.
Thanks!
