Hello Céline Epars.
Welcome to Microsoft Community.
I'm sorry to hear that you're experiencing issues with Microsoft Loop that prevent you from creating a page, I understand how frustrating that can be.
Generally, this kind of problem can be due to an issue with permission settings, and I would ask you to double check with your university's administrators. In the meantime, since you mentioned that you've tried things like clearing your cache and changing browsers, and they haven't worked. Considering that Microsoft Loop is still in public preview, I suspect this may be a bug or some sort of temporary instability. You might consider waiting for a while and the issue might go away on its own.
In the Microsoft Community, we provide you with technical support, but when it comes to Microsoft Loop, There is a specialized department that will deal with the products of the company or organization. We are confident that this team will delve deeper into this issue and provide you with more specialized advice.
- Go to the admin center at https://admin.cloud.microsoft. If you get a message that says you don't have permission to access this page or perform this action, you aren't an admin. For more information, see Who has admin permissions in my business?
