Test in a 4.5 or newer site As admin, go to Site administration > Activity modules > BigBlueButton > Pre-upload presentation There: activate  bigbluebuttonbn_preuploadpresentation_editable , keep  showpresentation_default  to yes, and activate  showpresentation_editable . Create 2 BBB activities with a document in Presentation content. In one of them, set 'Show presentation file on activity page' to yes and the other set it to no. In the app, open the BBB activities and check that you can see the document in the one set to Yes and you cannot see it in the one set to No. Please notice that the app doesn't receive the information to know if the file has been updated or not, so the app will always display the refresh button when the file has been downloaded.
