If you haven’t completed your ‘Business Information’ to your Facebook Business Manager Account, chances are:
1. When you apply for Facebook Business Verification, the business is greyed out & isn’t clickable.
or
2. The button isn’t visible.
Don’t worry, it’s very common and you can enable it by filling out your Business information.
The Button automatically gets activated once you apply for WhatsApp Business API using the Business Manager.
