Being as I don't have the luxury of internet connectivity as liberally as I would like, I've been trying to transfer music files from my Surface 3 to my Lumia 940XL via Groove. I keep getting an error stating I need to have software to move those files. I'm assuming it has something to do with the Groove Pass, and cached files, not purchased individual music files. like movies and tv. Just wondering if anyone has been able to transfer music with Groove like you could do with Zune?
