iTunes Match playlists missing from iPhone
As I am also running the DP for IOS9 I am not certain when this problem first arose. Its also complicated by the awful mess Apple has made with the Apple Music Service and changed terminology.
I have been careful NOT to activate Apple Music given the horror stories of iTunes Match libraries being 'damaged' and music lost from libraries.
So I am just running my ongoing iTunes Match subscription on my computers and various iDevices, as far as I can tell this is now called the Apple iCloud Music Library - as there is no longer any obvious reference to iTunes Match.
All my pre-existing iTunes Match playlists appear on iTunes on my computers, but none of them appear on my iDevices!
I never thought I would say this but I am getting to the point of considering getting rid of iTunes altogether, it has become such an awful piece of software, it would complicate device management a bit but it may well be worth the price to preserve my music library.
