Barring all the negativity coming to roost at present I found this on the iPad Forum when the copy/paste problem first surfaced.
Just place "iClear My Clipboard" from the App Store in your dock and leave it there for the duration as we all know by now
that most present fixes are hit and miss at best. I know because I've tried many if not all with no real positive results save for iClear.
Regardless it's a good place to see what you really do have on your clipboard before attempting to paste on.
Not saying it's the perfect fix but at least with it in the dock you'll have it whenever needed.
I'll add this to if I'm allowed.
The majority of the problems users have been having since iOS 8,(actually ios7!) have been cross the board problems
and not just specific to the older iPads. Just checking the web and other forums it's a well known fact sad to say.
Be it the newer faster chips aren't any more free of these glitches than our old feeble ones.
GIven the C/P problem is a major pain it's most certainly not the most pressing issue facing iPad & iPhone users at present
especially under iOS 8 and all its updates.
Fact is I'm loyal to my pad and well appreciate all it can do that and considering I have no laptop or iPhone so I'm totally
dependent on it for everything;(which does bite me in the dukis on occasion!) yet it's a choice I made and have stuck to.
But would I jump ship this late in the game after years with this very same pad and all we've been through together,
that'd be a big no.
Funny thing, even with all this...I still dream of the maybe never but well speculated about iPad 12" Pro; now how silly is that?
