The easiest way to find the issues is by trying to fetch the latest FB/Insta message and the latest lead.
This is how Zapier does it, and it helps us easily find the missed permission. FB API will present an error if permission is missing or for other reasons. Troubleshooting steps are as follows:
Check if all the permission are enabled for all pages.

Check Instagram page is connected to the FB page
Switch your logged-in user to the desired Fb page and go to this link.

Check if messaging is enabled.
