OK i have just tested again, and i have the same. Maybe i not updated the docs correctly or something did indeed change.
But looking at the docs, the data access expires actually isnt important for us
The following permissions do not expire:
- ads_read business_management
- configure_page_transactions
- manage_pages
- pages_manage_cta
- pages_manage_instant_articles
- pages_messaging
- pages_show_list
- publish_pages
- read_audience_network_insights
- read_insights ads_management
And scopes our app uses are: manage_pages, pages_show_list, publish_pages, public_profile
Which are all within the data access expire exclude list, except for public_profile, but that is just a standart of the facebook login, so also not important, as the app posts even when your logged out of facebook
So all in all, should be good to go.
Maybe you can mark the expire date in your calendar and report back a day later or so if all still works?
