Hello. I'm curious if anyone else is having this issue. I have a 128gb SD in my Lumia 830; the phone is running Windows 10. I have about 80gb of music and I tried copying it all at once to the SD card. When I did that, it seems like it didn't all copy correctly. So I started doing it artist by artist (taking a long time). I got about 1/4 of the way through, and now the albums don't show up in Groove at all when I add them. They show up in the files app, and they show up in other media apps, so I know they are there. Anybody have a fix for that?
