Our current application has been updated with a new version. This version works perfectly in the simulator and on test devices. But after the release in the appstore, all users that update will get one of the UIWindows completely black and unusable. If they force delete the whole application with settings, and reinstall it from the Appstore, the problem is gone. Is there anyone who knows what this could be, or how I could debug this? Thanks.
