When I click the link bottom "Open Microsoft Teams" in my inbox. Then it jump to Teams app. but on the top of the window it always has "initializing..." Also when I login with my personal account. It suggest me "You're not on Teams yet, but you can set it up for your organization." The problem is I don't want to set up but just participate in the team's meeting. My name is already in the team but I cannot see anything from my side.
