Microsoft has started to update some Project Online environments.
Now as Administrator of the PWA you will be able to change the Permission Mode that you want to use.
- Project Permission Mode
- SharePoint Permission Mode
Before only Tenant Administrators could do that.
Be extra careful trying to change the permission in Production Environment from Project Mode to SharePoint Mode.
By changing to a SharePoint Mode you will lose all configurations made for groups and categories and will be necessary do it again.
