Cannot post Text and Video posts
Incident Report for CoSend
This has now been resolved. It appears that one of our app domains had been blacklisted (investigating the reason) and changing this URL has fixed the issue.

Facebook are being non-responsive regarding this bug fix. As the issue seems to be related to our specific Facebook Developer App, we will be creating a new app and going through the approval process again. We are hoping that a new, separate app will allow us to circumvent this issue.

Please be aware that if this solution does work, your users will need to reconnect their Facebook Pages.
