Ok thanks, mine has had a problem for a while now with Safari, but only using NSC.
I have been using Chrome now and it's better than Safari, but I didn't use Chrome before the update.
I'm glad you have posted this, I thought it was only me.
Have you updated to iOS 8 ? Everything was fine with my iPad (which is less than a year old) until the update.
Loads of problems on my iPad mini since the iOS 8 update.
Almost useless now when viewing NSC on Safari, if I'm logged in it's really, really slow and logs me out if I scroll the page too fast, or when it feels like it.
It has frozen a fair few times when I have been typing a post.
Using Chrome...
