Hi @Jabbour, Steven ,
Thanks for reaching out to Microsoft Q&A.
The "New Wiki Experience" control lives in Azure DevOps’s preview-features toggles and is a gradual, server-side rollout there isn’t a tenant-wide switch in the Wiki settings today.
- Ask each affected user to click their user icon (top right) =>Preview Features =>find “New wiki experience” (or “Wiki: modern page editor” depending on your org) =>flip it on =>refresh the page.
- If you really need to automate it for your entire org, you can script against the Profiles =>Features REST API to set that feature flag for every user (this API isn’t in the main docs, but you can reverse-engineer it from the network calls your browser makes when toggling a preview feature).
Hope this helps!
