Turning on the Project Roadmap Feature

Hello,
I open my Microsoft 365 Admin Center. Then I click Services & Add-ins under Settings. I can see a line with Project Online. But when I click on it, I have an error message. The message says :
“Something’s wrong and we can’t load this page. Refresh and try.”
Could you tell me why I can’t open this page and how can I resolve this problem?
Thank you for your help

Our university uses Duo for MFA.  

tony-derricott we have a very small number of tenants with a unique Multi-Factor Auth setup that we are working on. do you use MFA?

What if it doesn't show up?
