Yep, copy and paste has gone totally screwy sinse installing iOS 8.
I can copy, but what is on the clipboard is something I copied 20 instances ago. I never know what is on the clipboard (until I paste it,) and it's hard to get something new on there, it's certainly not reliable.
I copy a dozen times and the new text copied never makes it to my clipboard, cause when I paste, I get something from days ago that was on the clipboard. How I hate new iOS releases, but I didn't suppose I could do worse than IOS 7.
It would be nice to post here my critique put to Facebook last night of iOS 7&8 that has made a return to iOS 6 highly desirable, but I cant now copy that post, and won't now re type it.
