I have an iPhone 6 running iOS 10.0.2. The 3D-touch feature to Messages is not working. I will type a message in the iMessage field, and then when I hold down the blue up-arrow send button, I do not get the pop-up with 3D-touch message options. It is working fine on Mrs. EDJ's iPhone6+ Everything else seems to be working normally. Any idea what is going on?
