Will all access tokens automatically be issued for 60 days, or will I need to continue to use:
https://graph.facebook.com/oauth/access_token?
client_id=APP_ID&
client_secret=APP_SECRET&
grant_type=fb_exchange_token&
fb_exchange_token=EXISTING_ACCESS_TOKEN
To exchange my short-term access token for 60 days version?
I asked a similar question a couple of weeks ago:
Facebook 60 day access token and Deprecated Offline_Access
It was answered by a Facebook Support Engineer who stated that enabling the “deprecate offline access” feature will give you 60 day tokens (no exchange required). On May 1st this feature will be switched on across the board and all tokens will be 60 days.
