Happens to me too. Easiest way to fix the problem is to restart the iPhone. Another way to access your pictures is to go to Camera, and view the pictures at the bottom left of the screen.
I've had to restart my iPhone a few times for this same issue.
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.
