Free Champion Rotation Button

After the recent client update where the champion icons in the collection became mini cards, I noticed that when you go to the home screen and click the free champion button in the top right it doesn't actually show you the free champions as it used too. Instead, it just goes to your champion collection not showing the free champs. As a player who doesn't have infinite BE and likes trying out new champs I'm not sure I like, I loved this feature and hope they fix it.
