Note! Please keep in mind that display name changing triggers the verification process by Meta. Meta will check if your display name matches the WhatsApp Business Platform Policy according to these naming guidelines.
In the last step, you’ll be notified that your name has been changed. Verification process can take some time, so the new display name won’t be shown immediately
