Recently my browsing functionality has completely broken. If I, for example, search for an artist and click the search result I can't get to the new artist page, or it loads the artist page and no tracks (just spinning wheel). Clicking on anything in the page does nothing. I basically can only listen to my playlists right now.
Additionally, I get CONSTANT upgrade banners. Upgrading will restart the app and...give me another upgrade banner. I did this cycle for 5 straight minutes yesterday.
