How do I keep content hidden from all apps on my lock screen

[Denise Lex]

When I had a notification on my lock screen the content would be hidden it would say hidden content I don't know where it came from but now it's gone and I would like to have it back

Try checking under settings>lockscreen>notifications>do not show content

Did you find the setting, suggested by chan?
Did it solve the issue?
