Text messages are not showing on lock screen on iPhone X
I have an iPhone X and since getting this phone, and especially when charging overnight, my text messages are not showing up on my lock screen. In fact, most of the time I don't even know I have missed texts until I go into the message app and see I have missed texts. I have updated all my settings to have them show on my lock screen and it still isn't happening. Please advise what I need to do so I don't have any more missed texts.
iPhone X, iOS 11.2.6
