PPT animations are supported, and will work. But quiz slides
are already loaded with animations and setting up the timing for
new animations is going to be a bear. Meaning, you would have to
take the time to figure out when you want the animation to happen,
put it in the correct place and then workout the timing for it. In
the end this may be more work than it's worth, but make sure you
have the custom animations menu open and add the animation to the
correct animation to create a group of animations that happen on a
certain click. That may be the easy fix, but don't know for sure it
that will work.
