Guest User Access? Will it be delayed until 2023?

To clarify why this is such a big issue; these are the steps that you currently need to go through each time you want to share a project with a new person (as of today; Mar 31, 2022):

1. Go to the "Microsoft 365 Admin Center" (this needs to be done by an admin/owner)
2. Create a new user for whoever you would like to share a project with. Most external collaborators (industry partners, etc) probably do not want to receive a completely new Microsoft account for the sole purpose of accessing a project. So in many cases this is where the whole concept fails...
3. Send that person the login info (username/password) for their new account, which again - they probably do not want to have in the first place
4. Purchase a Project Plan license, and assign it to the new user
5. Add the newly created user to the project that you would like to share (Open project --> Add as "Group member")
6. Send the URL link for the project, to the new user. And ask them to sign in with their new login. Then sit back and wait while they fail to do so - as they are probably already signed in with their work/university Microsoft account. And most everyday users do not quite grasp that they need first need to sign out of their main account, and then sign in again with their newly created Microsoft account (which only exists for accessing Project for the Web), before they can click on the URL link that leads to the project.
7. Rinse and repeat steps 1-6 if wanting to share a project with several people
