iMessages coming in out of order
A while back I had a problem with iMessages messages coming into view and going out of order (you could see a message come in and be placed above the last message I sent). It was fixed, I believe in 11.2.5 but has come back in the last couple of days on both phone (iPhone X) and iPad Mini 2 and my wife's iPhone SE. All devices have been on 11.2.6 since the day it came out but this problem just appeared in the last couple of days.
iPhone X, iOS 11.2.6
