Duo app keeps removing itself from the app drawer group everytime I don't do a lesson before noon and it's getting annoying.

You know when you're at your home screen and you swipe up the app drawer appears and you can make other groups there. I have Duo on my most used/daily apps groups and for the past few months if I don't do a lesson early it just disappears and I have to put it back to that group. Wth is this manipulation tactic?
