I have a Windows phone, and I have music in my Music folder in OneDrive, and it displays on Windows 10 Xbox Music, but for some reason it's not synchronizing to my mobile Xbox Music. Xbox Music mobile is just saying "It's lonely in here..." Any suggestions?
The issue has been resolved. It turns out the OneDrive and Music apps on my phone were outdated. Updating them fixed the issue and Music was able to access my library on OneDrive.
