in exactly the same position. Brand new iPad air 2 bought after selling my air 1 replacement unit for exactly the same bug. Diagnostics showed many issues with the old one and it has carried over to the new iPad Air 2. There are instances in Safari where I click on something and it won't go to the link. I have to pull down the notification screen about a third of the way down the page before clicking the link for it to work. Pulling down the notification screen also rectifies the gestural issue we are having - temporarily. When using procreate, there are apparent issues when using gestures (twisting the canvas for ease of painting, etc).
buggy as **** and I'm not happy with the lack of support. I have reset and reinstalled both of my devices into double digits now both over wifi and connected to a pc. It's still happening. My old iPad 3 for work has not updated to 8 as we aren't allowed to yet - that iPad works absolutely fine.
