Ahh thats great news! Thanks for the update @Flo13 and thanks for the quick fix Unity! :smiley:

Ahh that's a shame! Hopefully it'll get fixed soon... in the meantime I'm going to deploy with the new Cardboard support for iOS in b11! 

I'm just trying to publish with Unity 5.6.0b11 as well because of similar issues with 5.5. I've got it all working apart from when navigating to the Universal Menu and then back, the app freezes altogether. I've tested with a completely clean project...
