Returning commenters not triggering auto-reply on new posts..how to handle re-entry?

Hi everyone,

I've built a flow that works perfectly for first-time commenters. Here's the setup:

  • Trigger: User comments on a Post/Reel or replies to a Story
  • Story reply → heart-tap. Post/Reel comment → automated public reply (rotating set of 5) on any Post/Reel.
  • Condition check: does contact have tag "MF Entered Flow"?
  • If no tag → add tag → 3 min delay → DM #1 → DM #2
  • If tag exists → flow ends (no duplicate DMs)

The problem:

When a contact who has already completed the full flow comments on my next post (a new video uploaded the next day), nothing happens. No public reply fires. They're not re-entering the flow at all.

I've confirmed the tag is correctly applied to these contacts. The issue appears to be at trigger level, the flow simply doesn't activate for returning commenters on a new post.

I do not want to re-send the DMs. I only want the public comment reply to fire automatically for everyone who comments, regardless of whether they've been through the flow before.

My question:

Is there a way to ensure the trigger fires for every comment on every post, including from contacts who have already entered this flow previously? Is there a re-entry setting I'm missing, or is a second dedicated flow the right architecture for this?

Any insight appreciated.

Hi, ​@mf273!

 

First of all, I recommend you remove the tag at the end of your automation to let the user trigger new automations. If you always use the same tag in every automation, the condition will block any existing contacts that interacted with any automation before. And removing the tag enables the user to trigger other automations.

 

Now, the comment response happens AFTER a message is send via DM. This is a Meta restriction, and it is always necessary to send a first DM message to be able to respond the user comment. If a condition blocks the first DM reply, nothing will be sent as comment response. 

 

And, unfortunately, there’s no way to trigger it manually to the contacts that didn’t receive a response before… 🫠

(this is also a Meta limitation)

 

Hope this helps!
