If you have encountered error or correlation trying to activate “Project Web App Settings” feature on a SharePoint online site collection because you need to add Project Web App role to this site collection.
Let me show you how can add that.
In the below image it is enabled but follow the second image.
- You need to navigate to classic site-collections page to add the project web app role to site collection
- Add the following url to your SharePoint only admin url /_layouts/15/online/SiteCollections.aspx
Once you add Project Web App to site collection the feature is auto activated
