After todays update there is no more recorded dates in zwift (windows) for the aformentioned workout.
Just something to keep in mind for the next update you do.
I see exactly the same thing. I made it to week 12 day 1 only to see all progress lost. Obviously I have a record of my rides in the list of activities but the workout itself has no record that I’ve completed any of the sessions. It’s mildly frustrating.
