School admin

Hi there! We have subscribed for a school account and as an admin I can't see all the groups that other teachers have created. I think that as an administrator I should be able to see all the groups from the school. I have entered the code of several teachers to link my account with them, they already belong to the school (they joined by using my code) and even like that I am not able to see the groups they created, HELP! Thanks in advance!
