GeoGebraBooks become unstable in iPad!
I love the new launched GeoGebraBook function. However, I found that GeoGebraBooks becomes unstable recently! Very often it jumps out from Safari to the Home screen when I try to switch to applets in other chapters (e.g. in my GGBBook http://ggbtu.be/b83496). I remember GGBBooks were very stable in iPad when it first launched in Jan 2014. I don't know why it becomes so unstable recently. Can the Development Team look at this issue? Thank you very much!
