Currently any PDF stored in SPO or OneDrive that has a sensitivity label applied cannot be viewed with the Adobe Document Cloud PDF experience for Office 365 (https://documentcloud.adobe.com/spodintegration/index.html?locale=en-us). Users are forced to manually select to how open these PDF's in alternate solutions. This creates a frustrating user experience for those who work with many sensitivity labeled files.

When the Adobe Document Cloud PDF experience for Office 365 is enabled on a M365 tenant it acts as the primary PDF document handler within SPO/OneDrive, forcing PDF's to open in this solution. We are unable to change the default PDF reader on sites with this integration enabled.

Being able to view these labeled PDF's would create a much better user experience.
