Questions about on MS Graph limits on long filename/path (Document Cloud and SharePoint)

Hi We are starting to implement Adobe Document cloud for our clients when using Tesams and/or SharePoint, however we have now run into the MS Graph API limit, so opening some PDF files with Document Cloud fails.

I also found the following statement in the Adobe FAQ, regarding the issue.

Does anybody know what these limitations are, as i cannot find anything about it, also is there any timetable for when this will be fixed so we can open all SharePoint PDF's in Document Cloud.
