Issue Regarding Changes in Billing Plan for Copilot

I would like to seek your assistance in understanding a query from our product team. They are currently developing an AI agent using Copilot and have noticed that, in the Power Platform Admin Center under Licenses, the billing plan that was previously associated is no longer visible. Could you please check the current setup and confirm if there have been any changes to the billing plan or licensing configuration? As we checked on the evening of September 1, 2025, we found that a change had indeed occurred.

Previously, billing plans for Copilot Studio and pay-as-you-go models were visible under Billing > Licenses in the Power Platform Admin Center. However, with the transition on September 1, 2025, Microsoft shifted Copilot Studio billing from message-based units to Copilot Credits. This change has also affected how billing plans are displayed and managed in the portal. Could you please help us understand the issue further?

Thank you for your assistance!
