If you want to remove yourself as a project or folder member from a project / project folder, you can proceed as follows.
1) Open the web app on your PC / laptop and select the project folder or project. Then select the "Details" area at the top right.
2) In the view that now opens, scroll down and click on the "Exit folder" or "Exit project" entry.
3) Confirm the security prompt that appears by clicking on the "Yes" button and you are no longer a member of the project folder or project.
Good to know:
- If you are the only member of the project folder or project, you cannot leave it, but you can move it to the archive or delete it.
