Hello YOUNG LIM,
I’m sorry you suddenly lost access despite having a paid subscription.
To point you in the right direction, please let us know:
- The exact Copilot subscription listed under Services & subscriptions
- Where Copilot is missing, such as the Copilot app, website, Windows, Word, Excel, or Outlook
- The device and operating system you are using
- Whether any error message appears
Also confirm that Copilot is signed in with the same Microsoft account used to purchase the subscription. If you share a screenshot, please hide any email address, order number, or other personal information.
