If you are part of multiple Organizations in Cuez, switching between them is easy.

On the top left click 'Projects'. You will see the Organization you are actively using, hovering over it will allow you to select (or create) another Organization. Once you have selected another Organization, that one will load.

If your Organization has multiple Projects, you can switch between them just as easy, using the same menu on the top left.

See How can I switch between Projects? for more information if needed.
