My smart downloads don't work at all. I'm coming off the pixel 4 XL and now I'm on a Pixel 6 pro. It used to work now it doesn't. Edit 2/9/22: Pixel 6 pro still doesn't play the downloaded music. When I lose service. I have to reset my phone to get it to Recognize the downloaded files on phone. Update: Even though I pay for YouTube premium, I'm still getting advertisements. This app is the worst. At least they fixed the smart downloads thing now.
