It seems that the Visual Creator in Copilot for M365 has gone missing.

Thank you for asking this question. It was missing for me as well and I'm definitely hoping it is a bug that is being worked on as I've found it to be very useful.

It seems that other agents have also disappeared; Now I only see "Writing Coach" in the agents section. I tried different browsers, and the result is the same.

Same in Italy :(

We've had users notice this too. Is this an expected UI change or a bug?

Same.

I did see this today, and maybe it applies:

Users may be intermittently unable to leverage Microsoft Copilot (Microsoft 365) agents through any connection method

Issue ID: CP1029739
Affected services: Microsoft Copilot (Microsoft 365)
Status: Service degradation
Issue type: Incident
Start time: Feb 27, 2025, 11:00 AM EST

User impact
Users may be intermittently unable to leverage Copilot agents through any connection method.

More info
Users may notice that the Copilot agent either fails to load or disappears after initially appearing in Copilot.
 
If accessing Copilot through a web browser, users may refresh the browser to experience relief. If accessing through the Teams client, users may sign out and sign back in.

Scope of impact
This issue may affect any user attempting to leverage Copilot agents.

Preliminary root cause
A recent change introduced a misalignment with the mechanism responsible for allowing the service to parse models between systems, resulting in impact.
