It is a little difficult to explain, but before the latest update I could search for an artist or specific songs in my library and it would only put the searched results in my play queue and play only the searched results. I could no longer do that, if I search for something specific it would still play all the songs I have in my library and not what I searched for only. I will attach a screenshot if it's not clear enough. Basically I searched for a specific artist, before it would only play what I searched for even if it's on shuffle it would just shuffle what I searched for, now it is shuffling all the songs in my library
Same for me, ruined my experience in all my devices (Windows 10, Android 9 and macOS 10.15). Used to be so easy to just search my library and rebuild my play queue, now its a mess if I try the same thing.
