I already have an iPad Air 2 and a 12.9 inch pro. I got this for my daughter so she can play games and watch Netflix on here. It came with 9.3.3 and oh my is this thing slow. Should I somehow look for a file to downgrade it or have I just forgotten how slow this machine is? Also, are there any tips to make it faster on iOS 9? Lol. Thanks in advance.
