Hi ManyChat Community — I could really use some help.

Hey everyone! I know the ManyChat team has said they’ll be slower May 24–June 2, but I wanted to reach out here because I’m facing a pretty urgent issue and hoping maybe someone in the community can help or has experienced something similar.

Here’s what’s happening:
I’ve been using ManyChat successfully for Instagram automations (DM triggers, comment triggers, email collection) — everything was working beautifully until about 12 PM Eastern on May 23.

Around that time, someone on my team set up a separate Facebook Developer app for something completely unrelated (it wasn’t meant to touch ManyChat at all).

After that, my Instagram automations just… stopped. No replies to comments, no replies to DMs, no flows firing — though Messenger is still working.

Here’s what I’ve already tried (deep breath ):

• Disabled/re-enabled the Instagram and Facebook channels inside ManyChat

• Fully removed ManyChat from Facebook Business Integrations, then reconnected it

• Re-approved all permissions

• Tested fresh flows with new keywords, new posts, and non-admin accounts

• Tried both DM triggers and comment triggers

• Confirmed that even though ManyChat shows everything “connected,” nothing is firing on Instagram

At this point, I’m wondering if the developer app setup somehow messed with the webhook routing or permissions on Meta’s backend, even though I’ve reconnected everything I can on my side.

I also saw the Handover Protocol article and checked it, but the issue still isn’t resolved.

I’ve already sent a support ticket, but I have a really big post coming tomorrow and I’m getting a lot of automation requests piling up — so if anyone here has advice, has faced this before, or knows a workaround, I would SO appreciate your help!

Thank you so much in advance.
