The Recently Played section has disappeared in the last desktop player update. This is a very key feature that I used almost every day, as I frequently jump between user playlists that I don't add to my library, and now it is just not possible to find them again easily.
We’re closing this idea since it doesn’t meet one of our Idea Exchange guidelines, namely “Making sure your idea is clear”.
At this point, we don’t have enough information regarding what you'd like to see implemented.
Just to clarify, while there is no link in the left sidebar anymore, your recently played content should still be accessible from the Home page, below the shortcuts:
If that's not what you were looking for, you can submit your idea again, explaining how your suggestion is different from the existing feature.
You're also welcome to leave any feedback you have related to the New Desktop Apphere. Our developers are taking everything that's being shared in there under consideration, so any suggestions you have to improve the new experience will be greatly appreciated.
