I tried rolling back to older versions of AIR, but the problem still persists.
I'm starting to suspect this issue got introduced with the iPhoneOS8.1.sdk.
I intentionally did not update to Xcode6 when I updated to Yosemite as I wanted to keep building using the iPhoneOS7.sdk that was working fine for me.
Unfortunately my Mac had other ideas and decided to update to XCode6 in the background without my permission.
I found this out when my builds started failing to find the iPhoneOS7.sdk (which got removed when Xcode updated itself) and had to point them to iPhoneOS8.1.sdk instead.
My app is also a landscape only app, which I believe may also be a contributing factor as a number of people working with Unity seem to be encountering a similar issue.
Does anyone have any suggestions on how to possibly work around this issue?
Thanks
