Okay, so I've updated my music, installed it all on my microSD card, inserted it into my Lumia 830, restarted my Lumia 830, and...nothing happens. Windows Phone 8.1 is absolutely horrible with microSD cards, because they never refresh the information stored on them. They stubbornly insist that the hundreds upon hundreds upon hundreds of songs is something it can't recognize and until it accepts it I can't play my music. Is there any way to force the phone to refresh the information?
