John564479 Could this be a bug?
It could.
But adding lock-screen text works for some people, so there's a good chance that the settings matter.
John564479 The only thing showing [on] my lockscreen is the time (small clock, not the fullscreen one).
I have a large clock, but I don't think that's because of anything I chose. So maybe some option you have selected shrank the clock and is also hiding the text?
I have "Use device controls" off, and just one shortcut (the flashlight). I don't have any wallpaper at all. It might be productive to try turning things that are on your lock screen off.
And I guess probably before that... if any developer options are on, try turning them off.
