iTunes Match glitch since iOS 10 - can't download
I use iTunes Match but not Apple Music. Since upgrading my iPhone 6 to iOS 10, many previously downloaded songs from my library are not there but are "available for download" - I see them but they do not download when I tap that icon, even if they were originally iTunes purchases. Sometimes if I play/stream them for a few seconds I can then download them - but usually not. All iPhone and iTunes Match settings are correct per other articles.
I tried downloading those very same songs on my old iPad 2 using iOS 9 (the songs were not already on there) - and it worked exactly as it should. Please help. Thank you.
iPhone 6, iOS 10.0.2, null
