So on my iOS 5 iPhone 4S, wifi sync was brilliant. EVERY time I was home, on wifi and plugged my iPhone or iPad in to charge, the sync animation in the status bar popped up within 2-3 seconds and a sync would begin. Now, on iOS 6 (yes, I know, it's a beta) its VERY hit and miss. As a matter of fact I think it's only worked correctly maybe twice. If I manually initiate a wifi sync from the Mac, it'll usually work. If I manually initiate a sync from the iPhone or iPad it usually does not work. Again, I know it's a beta. Well aware. But I'm wondering if anyone has any ideas or similar/same issues? Have any of you managed to fix it?
