So you've uploaded to the latest operating system for iPhone and iPad and are super pumped to slam your first iMessage, or maybe invisible ink a love text. Instead you're just sending the closed caption version of the iMessage *face palm.
In order for this feature to work you need to check to ensure that REDUCE MOTION is turned OFF on the device in question. You can find this under settings > general > accessibility. If Reduce Motion is already turned off proceed to settings > messages. Turn off iMessage and turn it back on.
