I really don't like the customization of the Profile Card in contacts. I can no longer choose custom videos for call backgrounds that I used to choose from with no issue. The font styles are extremely limited and you can't change the sizing. If I choose a picture I like for the call background, then it automatically crops it as a square as if it's displaying the contact profile. So when I get a call, the picture of the contact is super zoomed in! And I can't adjust it!
