can’t join multiplayer minecraft pe

so i downloaded minecraft yesterday because i was gonna play with my friends because we haven’t played in a long time. so i made my account and everyone could join except me. it said that the feature was blocked and on xbox it said that i couldn’t add
people as friends. since me and my friend joined as a family, my friend was the parent. i tried again by her going onto her private settings and then allowing everything for me but it still didn’t work. hope you can help

:)
