So once the loading symbol appears at the right top corner, "downloading playlists..." will keep stacking up. The entire application becomes almost unusable, some button icons dissapear (for example the "More" button and also the "add next" and "add last"). Also I've noticed that "clear" button does not clear the queue like it should. But if I go ahead and try to remove one song from the queue, all songs from that queue list dissapear (something which "clear" button should do and not the one that should remove only one song). When going into the "updates" section, that's also opening a blank tab instead of showing the installed version. The only way to fix all these problems is to restart the app. But the bug happens again after a couple of minutes of trying to create a custom queue.
