Keyboard zoom shortcut either doesn't work or crashes

I was ridiculed for finding this bug on twitter by David, but here’s my official bug post. The bluetooth keyboard shortcut for zooming text size either doesn’t work or crashes dropbox projects with formatting on both iOS 10.3.3 and iOS 11 beta.

Also, David, get a better attitude when people are trying to report bugs.

That strikes me as a very strong mischaracterisation of the twitter exchange you had:

@Kinsey - thank you for providing the context and truth of the matter.

Which keys are you pressing that cause a crash?
