DCS for MSO365 - Shared PDF's wont open when the security is set to Can't Download

[sudosaurus]

Hello,

In reference to DCS for MSO365

When Sharing files in either OneDrive or SharePoint, if the sharing permission is set to Can't Download (Can View, but not Download), these PDF's will not open in Adobe Document Cloud:

We see this error page:

If the permission is otherwise set to Edit or Read, then the file opens correctly.

My initial thought is that Adobe must use the 'Download' permission to temporarily make the file available in their cloud and hence why this doesn't work.
