Why does not Huawei display any content of the news?

I got a Huawei Mate 20 lite and got the new Emui 9.0.1 update yesterday. Since then, however, no contents of my received messages are displayed anymore. The only thing I see is:

Whatsapp: 1 new message

Snapchat: 1 new message

Instagram: 1 New message

Likewise with Spotify is only: 1 notification. Does not mean I can skip a song over the lock screen!

I would like it again that the content is displayed as it was before z. B.:

Snapchat of Jacob

Or

WhatsApp: Paul

Does anyone know if and if so, how to do that?

This is a security measure from Huawei.

Let's say you're outside and sitting around with your friends, but do not want your friends to read your received messages while you're in the bathroom, e.g.

This security measure you can turn off in the settings.

Settings → Apps → Whatsapp → Notifications "Show on lock screen"

I hope I could help you, if yes I would be happy about a star!

@SoftHardware super many thanks for the quick response it worked great.

Now it would be nice to know if and how it works that the message is displayed when the phone is unlocked and the message is displayed.

Would be super nice if you or you would help me / t thanks schonmal☺️

I'm sorry, I answered too soon, unfortunately it does not work
