Office Add-ins should run in Chromium-based Edge, not EdgeHTML
At the moment addins run in EdgeHTML
Recently Chromium-based Edge has been released which is much faster than EdgeHTML
Add-ins should run in new, Chromium-based Edge.
Will it be "just done" at the next Windows update?
Thanks for the input – we’re working closely with the Edge team to use the WebView2 control for add-ins, and hope to have something to share later this year. Stay tuned!

Chromium's debugger would be a huge win!
