Hi Stacey

I think we can extend Reinout's answer towards Dataminer in general:
Is the MediaOps Solution considered to be WCAG (Web Content Accessibility Guidelines) compliant? - DataMiner Dojo

In short.
A few years ago, Dataminer was not WCAG2 compliant, I don't think anything has changed, nor do I believe there are any plans to be (fully) compliant in the future.
Should there be any accessibility trouble, issues or concerns, then it is advised to share them. That way we can adapt accordingly if needed.
