Miss an animated message? In iOS 10.1, Apple is adding a "Replay" button to the Messages app
In addition, messages can be sent with Balloons, Confetti, Lasers, Fireworks, and Shooting Stars in the background. But just in case you have received an animated message and missed the special effects, Apple is adding a "Replay" button to the Messages app in iOS 10.1. Press the button, and the message along with the animation will run again.
Apple even ran an advertisement last month focusing on its "expressive messaging." The commercial showed a lone balloon traveling in the woods and countryside until it hits the city, and meets up with a large number of other balloons. The herd of balloons then finds an open window, and ends up alongside an iPhone user who is receiving a Happy Birthday message with the balloons animation in the background.
