Here is a quick guide on how to remove a project from showing in ALL Unity Services! Completing this process will not completely delete the project, it will only archive it. What this means is that this project will be disabled for every Unity Service and not show in any of the Dashboards. There is also the ability to re-enable any archived projects so temporarily or accidentally archiving should not cause any issues!
If you are interested in only removing a project form Unity Analytics please refer to this post, Dashboard Update - Unity Services - Unity Discussions
First go to Unity ID and select the project you would like to remove from ALL Services.
You can then select Settings → General. Then click ‘Archive my project for ALL Unity services’.
At this point you will be prompted to type the name of the project you want to archive to confirm the action. Again please note, this will archive this project for ALL Unity Services!
In the future if you decide that you want to unarchive this project you can do so by going to Unity ID and clicking ‘Unarchive’. This will re-enable this project for all services.
