why i now see who send me notification on iphone x (while before i just recieve notifacyion from whatssup not who sent it)

Before the latest update if someone sent me biber/whatssup/message i recieve only notification from app but not who sent it. Now i see who sent message and with face id i see preview. I want full privacy but notifications on locck scr

I tried, wont work. U csn have either no previews at all or name and than preview once face id is turned on
