Sharing a Pro Account Project with Free Users: Access Limitations and Solutions

[great_void3000]

Hello everyone, good afternoon!

Recently, I completed a project and deployed it to the web on the client's Pro account. The organization is small, and the Director would like to share the project, which is on his Pro account, with three more of his collaborators (using free accounts). However, he is unable to do so, as the collaborators are unable to view the project and are being informed that they would also need a Pro account to access it. My question is: if he (Pro user) published the project on his account and shared it with a free user, will the free user be able to access the project in any way, or will they indeed need another Pro account?
