Hello,
we have a WOPI integration with Office Online which is working properly for pptx, docx and xlsx, but when opening vsdx files we get the following error:

We see in the WOPI discovery XML that vsdx edit url doesn't contain "IsLicensedUser=BUSINESS_USER".
Also when there is no Microsoft session active in the browser, for other documents the WOPI url redirects to office.live.com login prompt (https://office.live.com/start/....), but this redirect is not done for Visio.
Is it possible to enable Visio WOPI edit functionality?
Thanks in advance!
