This is a real disappointment.  While i support advancing the technology, visio online is not ready for prime time.  Just a couple of issues i've encountered with Visio Online thus far, which are not present in Visio Web Access:

• There is an undocumented limit on the length of a externally linked data fields on shapes of 250 characters.  This results in the timeout of Refreshing External Data on the Visio Online Document. Visio Web Access has no such issue.
• Linking of shapes between pages is very hit or miss in visio online.  Especially if the link is located in the template.

Hi, in this and other articles, "Visio Online File Viewer Web Part" is referred to, as if there is a web part named "Visio Online File Viewer", and I've been asked when that specific web part will become available to our tenant.

From reading references, it sounds like what is meant is that the "File Viewer" web part is to be used for viewing files in Visio Online (and this appears to confirm that is right: https://support.microsoft.com/en-us/office/display-a-visio-diagram-on-a-web-page-cecad64e-e0c4-49d0-93e0-acdd3709c57c). If it is, I request you please update this post and the page: https://docs.microsoft.com/en-us/lifecycle/announcements/visio-services-sharepoint-online-discontinued to clarify this.

Thanks for considering my request.

Hi Yana Terukhova - This page: https://learn.microsoft.com/en-us/lifecycle/announcements/visio-web-access-support-extended gives the retirement date of 2/10/23, yet also shows the sentence: "The retirement date for Visio Web Access in SharePoint* (in Microsoft 365) will be announced in the future."

With that sentence still in it, it sounds as if the hard date may still be awaiting a future retirement to be announced.

Please remove that sentence in the article so it's clear.  I've had 3 different people bring that article up questioning if the retirement is actually on 2/10/23 because of the misleading sentence noting a future date to be announced.

Also, I still see nothing about a Visio Online File Viewer Web Part, as my previous comment and other articles like https://support.microsoft.com/en-us/office/display-a-visio-diagram-on-a-web-page-cecad64e-e0c4-49d0-93e0-acdd3709c57c#:~:text=by%20using%20the-,File%20viewer,-web%20part note, it is the File Viewer web part. That's another point of confusion I've had questioned.

Thank you.

Hi Yana Terukhova,

I tested new approach against some SPO sites. File viewer works well in modern pages.

What about file viewer (part of page viewer web part) for classic sites? I could not get it working with all possible URLs extracted. Reference article for page viewer has "Displaying a file or a folder requires Microsoft Internet Explorer" statement, so I doubt the new way will ever work for classic pages.  

Thanks

I love how we keep going from rebust systems that were great, to barely there systems. Must be the 80/20 rule. Give them a product that is 80% ready.
