I just noticed the Play app updated itself (which I hate that you can't block or even get a notification it's happening), and it looks like they changed up the wishlist. I used to be able to add any app to it, which I did often so I could wait until I'm on Wi-Fi and then quickly access them to download. It seems now I can no longer add free apps to the wishlist. I can still add paid apps to it. Is this function actually that limited now, or is there something I'm missing to let me add free apps again?
