Hey! I've run into similar issues before, and it's not always an access permission problem.
A few things I'd check are:
* Whether the missing page has actually been connected to the same Meta Business account as the visible one.
* Whether the CRM/automation platform has been granted Lead Access for that specific page in Meta Business Integrations.
* If the page is using the same Business Manager and the same app authorization as the working page.
* Sometimes the connector caches the page list, so disconnecting and reconnecting the Facebook account (or refreshing the connection) can force it to fetch the latest pages.
* I'd also verify that the page has an active Lead Form attached, as some integrations only surface pages that have eligible lead forms.
If everything looks identical, I'd be curious to know which platform you're using (Make, n8n, Zapier, or another tool). That would help narrow down whether it's a connector limitation or a Meta Graph API issue.
