Ok so this is what is am seeing. I put my Bank widget back on and now and see what I think was going on. The Bank widget is never supposed to display the balance on the lock screen. When it was on before it would actually show the balance and never show the message that it can’t show it on the lock screen.
What it appeared to be doing was eventually getting to the point of trying to not show the balance on the lock screen but not getting there and that was blocking everything from displaying their data on the lock screen as well. This also looks to be what blocks the clock and the camera from displaying on the lock screen.
I would guess that this may happen with any broken widget timing out the display of data.
So please see if pulling widgets off till you get rid of the broken ones eliminates this clock missing on the lock mess.
