When I clicked on request authorisation from the application in the external account, it says delegation successful. So it should trigger the Sync facebook pages workflow, it does but facebook doesn't sync with the adobe campaign(Profile & targets -> Facebook).
I am using updated client console tool 8724.
I am logging into the Client console with the user which has Administrator rights.
the documentation link mentioned above is updated ?
Indeed it seems to have changed on Facebook's side. I will contact the product team to see if they are aware of that change.
To upgrade your build, you have to ask your technical administrator, who is in charge of the platform and will be able to perform the upgrade. Please update your build as it will surely correct some synchronization issues between the apps and try again with what you described in your first post. At first glance it seems to me that you chose the correct options.
I'll update you when I hear back from the product team to let you know if you should proceed differently.
Had confirmation from the product team that you should upgrade your build and then open a ticket to support if you still encounter your issue. In the meantime, I'll contact the documentation team to have the instructions updated for the next product release.
