three finger zoom

For low-vision users, the iphone an accessibility feature that lets you zoom in with a 3 finger swipe up. One of the users of some of the blindfold games mentioned that the zoom feature seems to override the program from responding to a 3 finger zoom, even though the program uses the AccessbilityTrairAllowsDirectInteraction.

Has any other developer seen this problem before, and if so, how did you solve it?
