We find that some of our customers never receive email or Facebook notification of us requesting access (Method 1). For those people we recommend the following 2 methods:
Method 2: Visit Your Page Roles to see if there is an invite waiting to be responded to in the Agency section:
Method 3: Give one of our staff Admin access under the User Roles so we can give ourselves Agency access:
Method 4: Try giving access from the Facebook mobile app instead of the website
From the Facebook Forum: I had no luck on my desktop but used the Facebook app for iPhone to add roles (Page Manager).
Please note that due to Facebook Terms of Service, we cannot post on your behalf until we have proper “Agency” access, not “User” access.
