Itunes 12.2 Won't Sync Apps on Iphone 6+
New to ios and I'm having trouble getting itunes to sync all of the apps that are currently downloaded onto my iphone. In itunes it shows a list of apps (a few I downloaded the first day I got my phone) under "sort by date added, etc" but everytime I do a sync it it says "copying blah blah" but no additional apps are ever added to the list. I have about 25 apps that are on my phone but will not show in itunes. I don't have any music, movies, contacts, etc that I'm trying to sync. Also, I do have the box checked "automatically backup to this computer."
I was able to go under "purchases" and click download from there and it will show in the list, but that takes forever. There has to be another way that I'm missing. Any help would be appreciated.
iPhone 6 Plus, iOS 8.3
