DONE Use the POST API instead of configuring it on the website Demo curl -i -X POST "https://graph.facebook.com/PAGE-ID/subscribed_apps?subscribed_fields=messages&access_token=PAGE-ACCESS-TOKEN"

Same problem + when i can set with POST API it request Page access token and when i try to get it in Graph Api, its again show me User token... Looks like a system bug
