I'm using iTunes 18.104.22.168. Yesterday I purchased 2 iPad Air - one for my wife and one for me. We have each previously used iPad2's. Thus the 2 iPad Air's are replacing the 2 iPad2's. We each have our own apple-ID. We have had the accounts for years. When backing-up I use my Pc and iTunes. Ofcourse we each have our own separate back-up. I have just restored my wifes latest iPad2 backup (made two days ago) to her iPad Air, and my latest iPad2 backup (made 6 month ago) to my iPad Air. For some unknown reason the number of apps restored to my iPad Air was only about half the number of apps I had/have on my iPad2. Why? To investigate I opened my apple-ID account in iTunes and had a good look at all the purcheses etc. I have made since 2009. The list shown is long and contains all apps. So this didn't bring me any closer to a solution. Still signed-in in iTunes, I went to "Library" mode. I opened "Apps" from the drop-down menu on the far upper left side, and I clicked on "All". Here I can only see a fraction of the apps, that I can see in my apple-ID account. Why? Furthermore, when I left click on one of the apps and choose "Show Info", it showed that the app was purchased by my wife, which is absolutely ridiculos. I left click on more or less all the rest of the apps shown. The Info shown was the samme in all apps. They were apparentely all purchased using my wifes apple-ID. None were purchased using my apple-ID. Once again this is absolutely ridiculos and very far from the truth. Why? I must admit that this rather confused me. To further investigate I disconnected my iPad Air from my Pc and logged out of my apple-ID account. I then connected my wifes iPad Air to my Pc. When iTunes opened I logged into my wifes apple-ID account. In "Library" mode I once again chose "apps" from the drop-down menu and clicked on "All". To my amazement the apps shown were exactly the same as the ones shown, when I was logged-in using my apple-ID. Why? Now I really confused. What am I doing wrong?
