Ive asked this before in general questions & on another website with no answers so gonna try one more time. Have Lumia 1520 8.1, never tried updating to 10 so upgrade bugs aren't gonna be the cause. When open music app on phone, the original app that is on phone when first get phone, has been Xbox music for me, all my music is gone. When tap on any of the folder options & search options only get blank screen. There are no images that show up, app has become completely empty & unusable. Did something change with music that app worked one day then the next day was empty? I know there is groove but I haven't tried as I thought was just a windows 10 thing. Going on a couple weeks of no music app, would like to get this figured out so really appreciate any sort of answers or help.
