Everything matches email wise. When we try and log into fortnite it says unable to sign into your account for xbox live

When I go to play Fortnite it says unable to sign into Xbox live but I have Xbox ultimate which has Xbox live so I don’t know why it’s not working

Hello.

For Christmas, we got a 25 dollar gift card. We added it in and in our payment options, it says we have 29.70 dollars in our account on settings. However, when we try to buy v-bucks in Fortnite; it says we have under 4.72 dollars and are unable to buy anything.
Please help us. Such a great way to start Christmas.

Also when I tried to see if it was the same with other games. I clicked on black ops 4 bundles to see if it was the same but it said that it's the normal amount of money we have 29.70 but it's still 4.72 on Fortnite. So it's a Fortnite problem.

I almost got there. I signed into my son's account on my ipad and was asked to accept the new terms when clicking on xbox settings. After accepting it says to finish your parent needs to sign in and accept terms, when i click next I then sign in as me but
it reverts back to my son's account. When I completely sign out and sign in as me, clicking on xbox settings does not bring up the new terms to agree. This is so ridiculous and a complete waste of money as the new terms have been since June so that's five
months of being unable to use xbox live! Does anyone have any ideas what to do or how I contact xbox to get help??

Just so I understand.

When you log into your account on the xbox and go to the fortnite game it brings up her account in game?

Did she start playing fortnite on your account on the original xbox maybe and it linked your xbox account to her profile on fortnite?
