My Question or Issue

I know that the last update changed how saved songs work, but I don't think it works correctly on my phone. Saving an album does not add songs on it to my Favourites (which, I know, is intended), but after saving each song on the album so that it appears in my Favourites and THEN saving the album, the songs disappear from my Favourites. I want to be able to listen to each album separately AND have all of my saved songs in one place so I can shuffle them. Please, fix this ASAP!
