ManyChat changed the trigger from "next post or reel" on Instagram to "specific post"

Hi! New here to the MC community. Love the service so far. Just run into a couple of snags and curious if anyone else has had the same issue. I had a post scheduled to go up on Instagram, and so, for the flow I created on MC, I selected “when someone comments on next post or reel” as the trigger. When I checked on the post after it went live, I realized that MC was sending the wrong DM to the commenters. Upon investigating further, it had also changed the trigger selection to “when someone comments on a specific post or reel.” It had selected the wrong post and was sending a different DM.

Has anyone encountered this or know how to fix it?

Thanks!
