On Monday I always plan my week workouts for the Build me up training plan and I look at the duration and the Stress points. In the Companion app you can see the workouts incl time and details, but NOT the Stress point/TSS. In the Zwift app you can see the same view, but it includes the Stress Points… I now always go to Whatsonzwift on mobile to see more details.
Can you please add this field in the Training plan overview and workout details in the Companion app as well? See mock up below:
