I have finally fixed this on my iPad.....
I performed a "DFU Mode Restore" - you can google how to do this - which fixed the problem. Before restore I made sure that iTunes was connected to store with the same apple id as my iPad would be after the restore.
I hope this helps - be warned however it does take a fair while to perform the restore fully as it needed to update IOS as well as load up all my apps, vids, music, etc.
Good luck to everyone else with the problem.
