the problem I’m experiencing is that contact names do not appear on whatsapp lock screen notifications. For example, if I get a message from Dad, whatsapp only displays the whatsapp logo and “message”, without displaying the sender. When I turn on message previews, I can see both the contact name and the message preview, but I used to be able to see just the contact name (“Dad has sent you a message”) instead of having to see the preview. This just happened as I updated to ios 11.3.1. Anyone having a similar problem? Thank you so much.
