Hello !
Microsoft 365 Family recently increased in price following the integration of Copilot AI features into the Office suite.
If you do not use these features, you can always revert to the “Classic” version by following this tutorial : https://support.microsoft.com/en-us/office/switching-to-microsoft-365-personal-and-family-classic-plans-58342e83-38e7-4cda-b63b-88604a8fb7ef
You'll go back to the Classic version of Microsoft 365 Family, which does not include the AI features.
Please let me know if you have any other question !
