I used it so often. The ability to see at-a-glance a show in progress and drill down to see how many seasons/episodes in total there are, and what I have watched and haven’t, and what’s in my collection and isn’t. And without a bunch of unnecessary graphics or clicking through multiple things. PLEASE BRING IT BACK!!!
I just realized too, that the new “Progress” page has a percentage displayed on each show that doesn’t refer to my progress of that show, but rather, the shows star rating, according to trakt. 
Me looking at a show that says 70%. Hey, I know I finished that show, WTH? Oh wait, I see, the percentage displayed has nothing to do with my actual progress of that show.
Another thing missing from the Progress page is the member rating and the original air date of the next episode. On V2, I could see the rating and see that “oh nice, this is a highly rated episode coming up”.
Also, I’m watching Taskmaster, prioritizing UK but also watching NZ and AU. When I finished the newest UK season, I couldn’t tell which one of the unwatched NZ or AU seasons were the next one up, without opening both in separate pages to find the air date of the next episode to watch.
it had a banch of nice statistics as a trakt page, you were able ot see if an episode was missing from your view history cause a bad scrobbler cause it said 99% complete, the same in collection, nice season + signs to view progress and %
all gone for no particular reason. i have asked about if it is coming back never got a reply.
