Hi ​@James97 ,
All messages sent outside the 24-hour window must be a "Template Message," as required by Meta.

One suggestion is to create a template message that encourages the user to reply right away. That way, you'll be free to continue with the rest of the flow.

Let me know if this helped.

​@rogerioaraujo on our test, we replied on the first message (template) but still did not received the 2nd message. 

Hi ​@James97 ,

Looking at the screenshot of your flow, I noticed that the issue happens because you added the second message (which is not a template message) right after the first one, without any kind of pause. As a result, ManyChat tries to send it immediately, which fails since it’s not a template message.

Below is a screenshot showing an example of how you can structure your flow so it works correctly. Between your template message and the next message, insert a user input block. This block requires some text, but you can just enter a blank space instead.

That way, the first (template) message will be sent normally, and the flow will wait until the user replies. Once the user responds, the next step will be triggered. Here’s the screenshot:

Hey, ​@James97 

I saw that this flow is triggered when a tag is applied to a contact, and then you send them a WhatsApp template because the contact hasn’t communicated with you in the last 24 hours.

That said, when you send a WhatsApp template without a reply button, the 24-hour window doesn’t reopen, which means the second message won’t be delivered.
