A couple of days ago I followed the WhatsApp implementation tutorial from the official documentation for my Odoo Enterprise instance, and everything went well.
I set up the WhatsApp Business account, created the templates and even verified the company in Meta.
However, although the connection test does not fail, it does not allow me to send messages.
I created a Marketing category test template in which only a welcome message would be sent. It has already been approved and I tried to send it to Client > Phone, but the message fails to be sent (the WhatsApp icon turns red) or I get a message indicating that the country or country code is not specified (when it is).
Do you have any recommendations in this case? I can't find documentation on the topic on the internet. Thank you so much.
