I would like an easier and better way to view missions and challenges in game and possibly even on the companion app. For example, currently, the wahoo climb mission is happening, but the only way to view it is at the opening home screen. I would love to be able to view it from the companion app and after I completed a ride as well to better keep track of where I am at with the missions. Generally you have to log back in to the game to view progress that you just made in the missions.
Definitely an improvement that could be made. Even better would be to make the status available on the My Zwift web page.
