If you are a project owner (or project owner manage delegate), when viewing one of your projects, you can manage access levels for members of the project by selecting “Project Management”.
The current list of users who are involved in the project are displayed.
If you click on any of the users you see their contact details including organisation details, as well as their current permission level. This will be either “view” or “manage”.
To Grant permissions to additional users in your organisation, or upgrade existing permissions, select the “Grant permission” button at the bottom of the screen.
Select if you want to grant view or manage permission to a user (select the ? icon to obtain details about the permission options) and then search for the project member in the available search bar. Note - you can only assign project owner permissions to members of your own organisation.
