The list of teams that presented in the "manage teams" page in the Team admin center includes 2 teams that are not visible to me as an admin in the Teams application. In addition, they are marked with a circle while all other Teams are marked with a square (see pic below). What does this mean? what is special about these Teams? Why can't I see them anywhere else?
I believe you are not a member of those teams. Check in admin center on those two teams if you are either an owner or a member of the team. Being a teams admin doesn't mean you see all teams within the teams application. Only those you are a member of
