Hello @Wilbur Pierce
Your daughter may be eligible, but Copilot requires users to be at least 13, and some regions have a higher statutory age requirement.
Please verify that her Microsoft account has the correct birth date and country/region, then check whether parental consent is pending in your Microsoft family group. Do not alter the birth date unless it is incorrect. Microsoft provides separate instructions for correcting birth dates and completing parental consent.
Also update the Copilot app, sign out and back in, and test her account through Copilot on the web.
Hope this helps. Please feel free to give me an update
