[Bug] Does not work on iOS 10.3 #4

I have been unable to SSH into my iPhone recently. I suspected this tweak. When I turned it off, I was able to ssh again.

THIS BUG IS 100% REPRODUCIBLE SSH works when DropbearAlert is disabled. SSH does not work when DropbearAlert is enabled.

When tweak is enabled: image

On the plus side, I've always wanted a graphical toggle for SSH :)
