Microsoft Sensitivity Labels block uploads

My organization has started mandating Microsoft 365 document sensitivity labels.

This creates upload errors when trying to upload documents with labels to Collaborator 15.0.15002.

In the "load_fail" image, you can see the "Uploaded Files" tab with an infinite spinning 'location' field.

In the "view_fail" image, you can see blank screens for the document view, and the comment field fails to apply comments as well.

This is likely to end our ability to use collaborator as a review tool (primarily for certification checklist usage). There is unfortunately not much code review work to maintain this tool.

Do you have any work arounds or possibilities for updates?

Thank you for any advise,

Neal
