is this auto DM working???

Hi ​@kihong 
I’m sorry to hear you’re experiencing issues with your IG Comment Trigger — I know how frustrating this can be.

Here are a few things I’d recommend double-checking:

1. Instagram permissions

   A quick fix that often helps is refreshing your Instagram permissions in ManyChat.
   You can do this by going to your ManyChat account and clicking Help → Refresh Permissions.

2. Follow the official IG automation troubleshooting guide
   This step-by-step guide covers several edge cases that can cause comment automations to stop firing and is very helpful for diagnosing issues like this:

3. Check for platform-wide issues
   Sometimes this is related to a temporary issue on Instagram or ManyChat’s side. You can check the current system status here:

4. One-time trigger behavior
   Just as a reminder, Instagram comment automations only trigger once per user per post. If the same user commented again, the automation would not fire a second time.

Hopefully one of these points helps you pinpoint the issue

Cheers,
