We have an App with multiple Ad-Accounts.

We use the Webhook 'leadgen'. The Callback-Url is verified and the hook works for most Pages.

We tried to add a new page recently, but no leads are sent. We have created a new access token with the following permissions:

pages_show_list, ads_read, ads_management, leads_retrieval, pages_read_engagement, pages_manage_metadata, pages_manage_ads

In the Access Token Debugger https://developers.facebook.com/tools/debug/accesstoken the page shows up correctly in the permissons table.

On the Lead Ads-Testtool however https://developers.facebook.com/tools/lead-ads-testing we get the message 'no Webhook-Subscripton for Leads Ads'.

In the Graph API Explorer the page also doesn't show up under Page-Tokens, even though we can and did chose it when creating the token.

The person creating the Token is an Admin on the App. The webhook works fine for all other pages.

What's going on?
