Message notification not showing on lock screen even though it's been allowed. PLEASE HELP

[AC Question]

I want my Samsung j5 to show my text message I recieve on my lock screen. I have allowed everything in settings but all my phone does is light up when I revive a text and the text is not displayed on my lock screen. I really need a solution. Please help anyone.

I have the same issue on the Samsung S8.

Has this ever worked for you?
