Question about Sharepoint PWA

Hi,

We are trying to connect Microsoft project to Microsoft project online. It seems that the project has to be synchronized with SharePoint. However, when we enter Project online a notification pops up " Change your default PWA site or request permission to the site ". We have added the user who has Plan 3 license as admin on Sharepoint PWA to get ride of the permission issue. After we did that and when we try to save a project from Microsoft Project Server to Sharepoint we receive the following notifications.

How could we solve the issue ?

Best regards
