Dear Dana K. Bisenbaeva,
Good day. Since you have teams for education i would like to get more information to understand very well the issue and provide the right answerPlease provide us with the following information. Thank you. 1-Are you creating a team from scratch and if yes which other templates are are seeing when you try to create a team.
Reference : Create a class team in Microsoft Teams - Microsoft Support If you can't see the class option check in your teams on web first. 2-Please can you try teams on the web to see if you can see the template. If you can't create on the web also, then it is an account issue.
You need to reach out to their EDU admin or IT department EDU to check the template policy assigned to their account. This will verify that the class template is enabled or not. Reference: Manage team templates in the admin center - Microsoft Teams | Microsoft Learn We look forward to your reply. This requested information will help us narrow down the scenario and find the right troubleshooting. We will continue to assist you based on the information you provide. I sincerely appreciate your patience and cooperation.SincerelyEben Ezer Tres | Microsoft Community Moderator
