I have a web application where the user links our website to their Facebook account so that we can publish content to their walls and fan pages. We were previously using the offline_access parameter but now it is retired and all of our user's access tokens are expiring after 60 days. It seems to me that all of our users will have to go and re-link their Facebook account after 60 days. Is there any way to automatically refresh the access token without the user's interaction?
