Usually it displays all the text but all notifications from all apps appear like this. How do I fix this?
Also, I downgraded from iOS 10.2 beta 4 to 10.1.1 and this started to happen.
Have no idea. Even disable "rest to open" does not automatically reveal notification texts upon unlock. Looks like a weird design change, cause I didn't notice it when upgrading from 10.0.1 to 10.2 beta 1.
I've tried restoring and restoring from backup, same issue. When I downgraded to 10.1.1 for the second time via the option + click tap to update method, the issue went away. Very strange. Seems like a beta bug.
