Would like to add how infuriatingly painful this is to use now. If I have a need to edit multiple players in a team, then I go into a team, then player 1, back to the team, then player 2 etc. This might be usable for 1 or 2 records, when I'm 50 records deep and having to now click "back" 50 times to get back to the team it's ridiculous. Please put this back to how it was or give us a 1-click option elsewhere to go to the parent record because this is not a good user experience.
