In Elements, you can have multiple Spaces (individual work environments). When you log-in to the app you are automatically logged-into your default Space. To change which Space is your default one go to the Space list in the main application, select the target space and click "Make default" in the right panel.
To ensure that you are always directed to your default space, make sure you open Elements using the app.q9elements.com URL without any extensions such as /t/1. This extension directs you to a specific space, regardless of any default settings. For example, /t/0 refers you to your personal/playground space, /t/1 is the first space you were invited to, etc.
