Attachment access from Mac OS and PC

Hello,

I'm running Presenter 11.0.0 on Powerpoint 2016. My project involves publishing a SCORM file for distribution on an LMS accessible by both Windows and Mac users. The preferred browser for my client is Chrome.

The issue has arisen when launching the material in Mac OS. Despite previewing the final presentation both before and after publishing, the attachments button (paperclip icon) is not displayed within the bottom ribbon of the player window. However, when launching the material in Windows, there are no issues. I've attached two screen shots to this post to highlight this issue.

Any suggestions on how to remedy this issue for Mac OS would be much appreciated - thanks!
