🔹 Two terms to learn. USL is the user subscription licence, the M365 Copilot seat and everything in it. UBB is usage-based billing, credits and pay-as-you-go. Microsoft have now written that split down as the model, so it isn't going away.

🔹 Chat and Cowork are merging, and Copilot will decide which one runs your request. Chat is in the seat, Cowork is on the meter.

The switch you used to flick was the thing that started the bill. 🔹 If your spending policy has "auto-apply new services" on (it's the default), every new metered thing Microsoft ships lands in it without anyone touching the policy.

🔹 Code looks like App Builder reframed: dashboards and small line of business apps. Building them costs credits, and running them will too. 🔹 Scout is now Autopilot. Cloud-hosted, its own identity, its own memory, consumption based. Less "my Copilot got a memory", more "I've hired a colleague".
