In the last app updates, it lost tracks from my Library.

Open an artist, and see Artist Profile, not my tracks from this artist, as old versions.

What kind of library is this? I mark tracks to see in my library.

If I need to open every album of every artist, then not is a library.

In windows, all still OK.

Please back to old library.
