Registering the WhatsApp number needs a two-step verification PIN
Why it happens
Registering the number on the WhatsApp Cloud API needs a 6-digit two-step verification PIN, and no PIN in the right format was entered.
What to do
Enter a 6-digit PIN: the number’s current PIN if two-step verification is on, or a new PIN of your choice if it is not.
