DocumentCloud for SharePoint Online

Dear Community,

Dear Adobe Support,

we are evaluating Adobe DocumentCloud Integration for Office365 / SharePoint online.

for this we used the installation guide and added the App to our AzureAD: https://documentcloud.adobe.com/o365pdf/main.html?trackingid=X6FJHVD2&mv=in-product&mv2=acrobat

I experience the following behaviour:

- Opening a PDF in userse OneDrive does open it in DocumentCloud

- Opening a PDF in a Teamwebsite does open a blank tab without loading the document. I can also choose in SharePoint to "Open in Browser" which works. But then it is not opened in DocumentCloud.

Already tried in different browsers, on different workstations, with different users -> same experience.

Does anyone has the same experience and a solution?

Thanks,
Chris
