Project Plan no license user issue

Hello Alvin_Pang ,

The Office 365 users without a Project Plan license are limited as you have seen, there is not way to control what they have access to: https://learn.microsoft.com/en-us/project-for-the-web/office-365-user-view-access-to-project-and-roadmap If you want them to update other data, you will need to grant them a Project Plan license.

Regarding tracking if a task is completed late, there is no time phased data entry (timesheets etc.) or baselining in Project for the web, so out of the box, you are not able to track this. This is available in Project Online though.
