iMessage Effects, both bubble and full screen, were some of the most fun elements in the updated iOS 10. But on day one, we discovered that they just didn’t show up for a lot of users. People who had the “Reduce Motion” accessibility feature turned on. A lot of users did this after iOS 7 came out. This setting removes the animations from the OS. Like opening and closing apps. But to be able to send Lasers to group chats, these users now had to disable Reduce Motion.
