How do I upgrade/change my organization plan ?

Organization information is located on the settings page

Navigate to the Settings page via either the Left Side Panel or by clicking your avatar in the top right and selecting settings.

Once in the settings there will be a "Payments" Tab if you select that you will see your current plans status and information.

Clicking "Edit Plan & Payment Settings" will navigate you from the site to the payment portal where you can change your plan amongst other things!
