Quick answer

If the Copper sidebar does not appear in Gmail, the extension is usually disabled, hidden for that inbox, or not signed in.

How to fix it

Try these in order — the most common fix is first.

  1. 1. Confirm the extension is on

    2. Pin it to the toolbar and click it to sign in

  2. 2. Check hidden inboxes
