As a former CoPilot Premium user I previously had the CoPilot button within the M365 apps. As of today I now see this functional for chat once more within the apps - great addition! Colleagues with M365 E3 licenses (but not CoPilot premium) who are on the same release channel and build version do not see this button. Is there anything additional they can do to expedite rollout?
