On the other side, if the user already has a Project Online license, and doesn't have sufficient permission to access the Project Web App, in this case, it will get an "Access Denied" error, not "Sorry, you don’t have a license to use Project Web App" as shown below:

So, in your case, I think it's mainly a license issue for specific users, not a permission issue! and for users who get "Sorry, you don’t have a license to use Project Web App", you should make sure that they have a Project Online License based on their roles:
- PWA Admin who able to create and manage a PWA instance requires Project Plan 5.
- Project and Resource Manager require Project Plan 3.
- Team Members require Project Online Essentials.
In case, you are sure that every user has the required project online license, so I suggest to contact your Microsoft License Provider to review your current subscription and specify/renew the required license that you need to let your team members access Project Web App and Project Site.
Also, you can contact Microsoft Office Support Team at Microsoft Project Support.
