The Facebook support team
has confirmed my problem, and is investigating.
I am now solving using the graph api to get the desired message information using the mid
GET /v8.0/{message-id} HTTP/1.1
Host: graph.facebook.com
https://developers.facebook.com/docs/graph-api/reference/v8.0/message
Ex.
GET
https://graph.facebook.com/v8.0/' + mid + '?fields=message%2Cfrom%2Csticker%2Ctags%2Cid%2Cattachments.limit(10)%7Bid%2Cimage_data%2Cmime_type%2Cname%2Cfile_url%2Cvideo_data%7D&access_token=XXXXXX
