Support said that new progression logic and new post-workout survey were recently deployed. And support manually set my Wed workout to moderate.
And interestingly I now have progression levels waking up:
and Echo -3 from June 11th is now showing PL updates:
along with PL updates for January/February custom outside workouts (from TP):
No workout scoring starting March 1st as I disabled TP-to-TR workout sync on Feb 27th. Re-enabled on April 27th and workout scores reappear but no PL for custom workouts except those in Jan/Feb. So I suspect that generic outside workout support is getting closer.
