I developed while back a facebook graph api app that used the conversations edge to read messages and then reply back, this was done using the v2.3 version of the API.
Back then the API at
https://developers.facebook.com/docs/graph-api/reference/v2.3/conversation/messages#publish
stated that:
Note that a page can only reply to a user's message. It cannot initiate a private message with a user. Also, a page can respond not more than twice to a user's message before the user has replied back
But now i have to upgrade to v2.4 and i can't seem to find anywhere the above statement.
Does anyone now if this limit has been lifted?
