Issue Status: RESOLVED
Issue Description: Users may have been intermittently unable to copy an agent created through the Agent Builder into the full Copilot Studio.
Final Update: 15/06/2026 10:50:00 AM – Microsoft has completed deploying their aforementioned targeted fix and confirmed with their service telemetry that this issue is resolved.
Scope of impact: One percent of users who attempted to copy an agent created through the Agent Builder into the full copilot studio were intermittently impacted by this issue.
Root cause: A recent change related to how version strings were read prevented the service infrastructure from identifying which features were available to users.
Next steps: Microsoft are investigating the impacting recent change to pinpoint why this issue wasn’t caught prior to deployment so that they better prevent the inability to access some features in the Microsoft Copilot Studio Agent Builder in the future.
