Dear PS_1818,
Good day to you and thanks for your post in Microsoft Community. I'm sorry for the inconvenience you've encountered. To better assist you, could you please provide more details such as:
- Which platform do you use? Desktop or web app?
- Would you mind giving a screenshot about your issue? I want to clarify that if you do not have a button for class or have it but grey.
- About creating team, could you create a basic team normally?
- Did the issue happen before? It means you created a team class before but now you cannot.
- Does someone in your site have the same issue?
- What is your license linked to your account?
- Does your tenant allow users to create Office 365 groups?
Once again, I sincerely apologize for the unpleasant experience. I look forward to your information and if you have any questions, please feel free to reach out to me - I’ll be happy to assist you. Wishing you a wonderful day.
Best regards,
Daniel Vo - MSFT | Microsoft Community Support Specialist.
