New iTunes App installation After updating my iTunes to the new 12.2.0.145 I can no longer manage the apps on my iPhone 6+ from iTunes.  The apps show up and there is the install/uninstall buttons beside them, but they are grayed out and unavailable.  

Anyone have any suggestions on how to fix this?
Did you update to iOS 8.4 yet?
If not, now would be the time.  

In iTunes - sync; backup; update. 

If you're already on 8.4, then sync; backup; restore.
