Xbox Live Sharing Not Working For Fortnite

yes i signed in with the same xbox but my brother was is not playing at the time or signed in anywhere

Now once, i have not done this anytime in the last year

how many times have you game shared in the past year

Did you sign in his account and yours on the same console? Because I'm game sharing Xbox live to my friend I can't be on my account when he is trying to play

She was the first to log into fortnite on the xbox. When i tried to log my epic account on it from my profile, it just brings up her fortnite account even if im on my profile. We share one xbox with 2 different microsoft accounts and we share the gold
for multiplaying. The only way to log her out is to unlink it from the epic games website. I can play everything else independently, but so far have been unsuccessful on having two fortnite accounts on one xbox, even on two different accounts. I know how the
sharing works, This is Fortnite specific on ONE console.
