nope I have the knock code. Anyways I realized what was causing it, it was something to do with a certain email synced, its complicated but it's fixed now!

Do you have a PIN or anything? I think that makes it so everything is hidden until you unlock.

I noticed today that my text messages contact and sports app notifications didn't show the content on the lock screen anymore. Instead, it tells me what app it is and says "content hidden" anyone know how to change it back to showing all notifications?

In my settings, I turned on show all notifications but they're still hidden.
