I wrote a feedback (amongst numerous other feedbacks) to Apple that after Beta 4, Real Racing 3 crashed on opening and lo and behold, that evening I got an email from an Apple engineer saying that Beta 4 was fully compatible. I emailed Electronic Arts ( the issue is well known) as its on their support site, and got the standard answer that iOS Betas are not compatible with the game.....
I informed them that the game has been playing perfectly throughout all the betas, obviously they didn't like my reply.... As they replied that I should roll back to 9.2.1....
Great customer support.....
