In late November 2017 many iPhone X users have reported that their text typing is lagging when they are using iMessage or texting on their phone. A user will be typing a text and it will get stuck and lag behind what they have actually texted. Some have even reported they have finished entire sentences before the letters and words are coming up in the text. Is this something you are experiencing? If so, when did you first start to notice this? What iPhone are you using and what operating system have you updated to?
