So we all know that Apple changes things all the time for whatever reason. In iOS 8.3, they removed access to the documents folder in each app. This would allow people to use a program like iexplore to go in and manually retrieve game progress and game saves (at least that's how I would use it).
I've upgraded to the GM of iOS 9 and have some odd glitches that I am not sure that are related to either the GM or not. I basically want start from scratch with no backup. However some of the games I have from Rovio do not have a way to backup the game progress or restore it. Some of them do either via Rovio accounts or Facebook connectivity. I've literally spent years on some of their game progress. So what to do.....
PS - start using iCloud backups for your saved game progress devs! Yes I know it's been a pain in the past, but still. At least offer something...
