If you are part of multiple teams or organizations, you can switch between them quickly and easily. To do so, click your profile circle on the top right of the header. A context menu will show up on top of which you can find the team switcher. Simply click on our current team and you will see the others you are a part of.
If you can't find your team in the dropdown menu, make sure you are logged in with the correct email address and reload the page.
