iTunes 12 play counts not updating
So... my home Mac hosts my main iTunes library and was on the last version iTunes 11. I connect to it from my Windows laptop in my office, with the Home Sharing setting to update play counts and dates turned on (I need this for certain playlists to work). My Windows machine was also on the latest 11.xx version. After upgrading the Windows machine to iTunes 12.01, this feature stopped working. I can play music from my main iTunes library on my laptop just fine, but they don't get updated with the last play date and count on the main library - like it did earlier this morning.
I then upgraded iTunes on my Mac that hosts the iTunes library and it's now on 12.01 as well - but the problem is still there.
Anyone else have this issue? This isn't the first time I've had an iTunes upgrade break this feature.
Is it ever safe to apply an upgrade to iTunes without worrying about a key feature not working any more?
