Messages shows "Message sent with Balloons" instead of balloons effect

My phone is showing "Message sent with Lasers" and "Message sent with (X effect)" rather than the actual animation. I've downloaded iOS 10—what else do I need to do to see the messages?

Solution 1:

It's likely because you didn't like those zoom effects in iOS 7...

You'll need to turn off "Reduce Motion" in Settings app > General > Accessibility > Reduce Motion. Then your incoming Messages effects should go off as planned.

Heads up: This will re-enable the parallax icon effect on the home screen (where the background moves behind the icons). But don't worry about that old effect where the screen would zoom into app icons—that's long gone.
