Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello,
The AI-powered features in Microsoft 365 apps are available only to users who are 18 years of age or older. Users under the age of 18 can still use Microsoft Office apps, but they will not have access to the AI-powered features, such as Copilot in Office 365.
You can learn more about managing AI features for your daughter's account on the Microsoft Family Safety settings page here:

Regarding the second issue:
"Why I have to login each time when I change microsoft page to access various services?"
This could be a browser-specific problem.
Try clearing your browsing history, cache, and cookies. Then, sign in to your Microsoft account again and try accessing the services.
