Hi, ​@Sasha Felin!

Does this message look like something “standard” or is it something you used in past automations?

If it seems to be something standard, you could check if a Default Reply is active:

Also check if you haven't something turned on directly on Meta Automated Responses: https://business.facebook.com/latest/inbox/automated_responses

It could also come from other automation tools (if you use something extra).

Hope this helps you… And if it still continues, send us more information, screenshots, etc. It helps a lot!

(Também pode ser em português )

Thank you very much ​@Fabio Gaulke , the problem was actually within META, I configured the wrong campaign.
