Pessoal,

Não estamos conseguindo enviar mensagens ativas para alguns contatos, pois está retornando o seguinte erro:

User's number is part of an experiment: Failed to send message because this user's phone number is part of an experiment

Alguém já viu isso antes?

O que a Meta fala:

Marketing Message Experiment

Starting June 14, 2023, roughly 1% of WhatsApp users will not receive marketing template messages from any business unless one of the following conditions is met:

• a customer service window exists between the customer and the business
• an open marketing conversation exists between the customer and the business
• an open free-entry point conversation exists between the customer and the business

If you send a marketing template message to a customer who is part of the experiment group, your message will not be sent and you will not be billed for it since no conversation was created. Instead, you will receive a message status undeliverable webhook containing error code 130472, notifying you of the failure.
