Hi,

I have my app linked to my Facebook Business page to share photos directly to it. Using the share dialog API, I used to be able to share photos on my FB account and receive back the confirmation that it was shared, enabling me to clean my app's backoffice of the shared photos. But recently, since you changed this dialog API, it stopped working. The photo is shared, but I do not receive that information back from FB. How can we fix this?

Additionally, after several months of problems I recently managed to share the photos (with the above problem), but a collaborator of mine is not able to do it, although we already gave him full access to the FB page to try to deal with this issue. It asks to turn on the Third party Apps, Website and Games (which we already checked it is turned on), but when clicking on it nothing happens, and that option is not showing up in the settings in the facebook page itself, only in the personal page.

Another issue: why does the url of the share popup change depending on the user that is logged in? In some users the url starts with "https://www.facebook.com/dialog/share" and on others the url is "https://www.facebook.com/share_channel" ?
