I'm a blogger (see blog below) and I don't know the cause of your specific issue but I know an easy workaround. Go onto your phone and into the app store app. Go to the updates section (on right side of bottom bar) and hit purchased.
Go to the "not on phone" section. You should see every app you ever downloaded on your account that is not on your device. Just tap the cloud( the button) next to each app you want to download and you should be all set.
Enjoy your iphone and come to my blog for some great app suggestions and more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
