No Portal to map in Public group

Hello,

When I am in a Public group i can Not See the Portals to the map (endgame). This worked a view days ago, seems Like this is since Last Patch. When I Open a Public group myself, others are joining the group but nobody is Entering the map, so it seems Like they dont See my Open map, too.

A fix would be nice. Playing on Xbox series X.

Regards
