I just found out that I use a Youtube-Brand account and have all my playlists stored there. Now you can transfer all music uploaded to Google Play Music to Youtube Music with just one click. Cool. But unfortunately it doesn’t work with the Brand account. I have to use my “other” YouTube account. Okay, whatever. But there I miss all the other playlists I have created over the years. What a bummer. Why does everything always have to be so complicated?
