Copilot Cowork mode has disappeared from the account

The plan name matters here: being the Family subscription owner does not, by itself, establish eligibility for Cowork. Microsoft’s current Copilot app update guidance says Cowork for personal accounts is a Premium or Pro feature in Preview; Personal and Family users lose access to running Cowork tasks after the transition.

First, check the exact subscription name under your Microsoft account’s Services & subscriptions. If it is Family, the documented eligibility change can explain access disappearing; a local reinstall or settings change would not add that entitlement. Previous Tasks conversations and content should remain viewable, although running them again requires an eligible plan.

If the subscription actually says Premium or Pro, test Cowork in the browser using that same personal account, then return to your existing support case with the plan name and screenshots. Your post alone cannot establish a rollout bug or licence-sync fault.
