Are you referring to this in the ‘Known Issues’ section of the Adaptive Training thread?
That particular one has been resolved, so if you’re still experiencing it, I’d check in with support@trainerroad.com to make sure something isn’t amiss.
This was on the team’s radar but not sure where we are currently. If there’s new information I’ll definitely provide an update!
EDIT: When you say completed a ‘Stretch’ workout, do you mean changed the workout assigned to a more or less difficult one? I may need you to get in touch with support for this so they can look into your calendar, what was assigned, completed, and how it effected the logic. Sorry for the trouble!
