Google Sheets Canvas no longer works in Embed tabs?

Google Sheets Canvas no longer works in Embed tabs.

A Google Sheets Canvas worked inside an Asana Embedded Media project tab yesterday, but today the same Canvas displays: “Canvas tabs are not supported in embedded sites.” Regular Sheet tabs still work.

I was testing Asana’s new Embed tab type with Google Sheets (this works great! love it!)
I created a Gemini Canvas within one of the Sheets and, initially, the Canvas worked directly inside Asana. It was a really promising way to create a custom interface over Sheet data without leaving the project.

Today:

  • Regular Google Sheet tabs still load normally.

  • The Canvas tab no longer loads.

  • Instead it says: “Canvas tabs are not supported in embedded sites.”

  • Nothing changed in my Asana setup or the embedded URL.

Has anyone else tested Google Sheets Canvas in Embed Tabs and seen this?

Has anyone tried any work-arounds?

Thanks!

Hi @B_Dorsey this is actually the first I am hearing about Embed tabs and don’t seem to have this as an option in my workspaces. Is this a Beta feature you got an early preview for?
