Whenever I get a WhatsApp message with my iPhone locked, I can't see sender's nickname as set by them in their WhatsApp profile. I used to see it previously, but now I see the name which I have saved the contact with in my Contacts list. I would like to get back the ability to see nickname instead of contact name. I don't want to delete the name in my contact list I just want it to be like it was previously.
How can I do this?
