The update STILL didn't fix the issue of no messages showing on my lock screen

[Frustrated]

I got excited because of the new update thinking it would fix the issue I had after installing lollipop where **EVEN WITH THE SETTING TURNED ON** the lock screen doesn't show the previews of my messages. It actually doesn't show anything at all. Once again before someone brings it up, I checked literally 3 minutes ago and the setting IS turned on. I even turned it off, restarted, and turned it back on after the restart. No luck. I'm pretty sure this is something not fixable until the next update but I can atleast ask is there's possibly something I can do to fix this?
