I have spent the last 2 hours trying to resolve this. The screenshot below shows the issue.
In Facebook business manager it says I am the admin. The only thing weird about this is that in Facebook settings 'Page Roles' my role is 'Custom' instead of what most people see 'Admin'. Could this be the issue? If so, how do I resolve it? Or is something else causing me not to make this connection work?
With other sites I never had an issue with this. Help would be very much appreciated!
