Since updating to iOS 9, IF is VERY lagged. It’s very choppy too. I get messages like 20-30 seconds after sent and cannot respond for 10-15 seconds. Common problem with iOS 9?
Moved to Bugs. :)
Im not sure if IF is supported on IF yet
I don’t think it’s a bug. I believe IF combined with iOS 9 is too much for the RAM in the iPads. I’ve turned down all the settings to their lowest. I was able to ATC for 45 minutes without too many problems. iPad Pro coming soon.
