There could be a few reasons why WhatsApp is not displaying names. It’s possible that you have not set up your contacts list correctly. Additionally, if the contact you are trying to view has changed their profile information, the name may not appear. You may also want to check your settings to make sure that your contacts list is configured correctly. Additionally, it is possible that your phone or the WhatsApp app may be having technical issues. To resolve this, try logging out and logging back in to the app or restarting your device.
