Invites come back on my screen and not friends

When my daughter sends me an invite from her iPad to my iPhone, it pops up the invite on her screen and not mine.  I can send her one, and it pops up for her but she can’t join.  I can see her world and try to join and cannot.  This just started to happen, we have signed in and out of Microsoft accounts, reset router (we are in the same house), deleted and reinstalled the app, to no avail.  Any help would be appreciated.  Thanks!
