Transfer Purchases no longer working
I've had this issue, since updating to iOS 9 GM-candidate, and the last version of iTunes, and it persists now to iOS 9.0 and iTunes 12.3.0.44 (today's updates).
Clicking 'File->Devices->Transfer purchases (etc...)' does nothing.
Is anyone else experiencing this?
I'm trying to back up a couple apps to my iMac, as they have been taken off the iTunes store, and I would like to keep a backup.
