So we have these ride reports which come up after every ride before quitting the application. However, once you quit, you won’t be able to view the ride report again. I see that this feature is there only if you signed up for a zwift training plan where you can compare it with the planned workout to see how well have you done as shown below(found this picture on rcuk website):
When it comes to workouts which are out of the training plan, you just get to see the report once only.
So if the new feature gets approved, it would be nice if it is in the above format itself.
Regarding races, I am pretty sure zwift power will be back soon, but the ride report would be same as a workout/ride when not following a zwift training plan.
