🔴 Instagram Webhook Issue: Reactions received, but Text Messages ignored (n8n) Message:

Hi everyone, I’m looking for some expert advice on an Instagram Automation I'm building with n8n and Meta's Graph API.

The Issue: My n8n Webhook is successfully receiving message_reactions. For example, when I react with a ❤️ on a message, the webhook triggers, my AI Agent processes it, and sends a reply back on Instagram. However, when I send a regular text message, the Webhook receives absolutely NOTHING (the node remains in 'waiting' mode).

Current Setup:

App Mode: Development.
Permissions: 'Allow access to messages' is toggled ON in the Instagram Professional account settings.
Webhooks: Subscribed to the messages field (v24.0).
Testers: Testing from an 'Instagram Tester' account added in the Meta App dashboard.
Crucial Bug: I encountered a 'There was a problem accepting tester invite' error on Instagram when trying to accept the invitation for the test account.

Since reactions are passing through, the connection is alive. Why would Meta filter out text messages while letting reactions through? Could this be a ghosting issue with the instagram_manage_messages permission in Dev mode, or is it strictly tied to the tester invite bug?

Has anyone encountered this specific 'partial' webhook behavior before? Thanks!
