Very odd thing. I have successfully launched the Mix Reality Sample code but today when I opened it up, I was unable to scan the environment I was in. The touch menu is simply unresponsive, tap away as much as you want. Odd.
I did a rebuild from xcode. Same problem.
Deleted app from iPhone. Rebuild.
It works! Scan the environment. Muck about a bit. Close app.
Let's try that again.
Launch the app and load the previous scan - menu is once again unresponsive.
Try rescanning the environment - can't menu unresponsive.
What am I missing?
(xcode: 8.3.3 (8E3004b), iPhone 6s 10.3.2, OSX 10.12.5)
