I had the same problem and changed my Allow explicit content tab to on. But unfortunately its still the same situation, if someone can help I'd really appreciate it.. I have a Huawei P20 Pro and I only use the Spotify app on my phone and in my car.. I also attached an image to show you what I see. All 4 were gray now just 2 after I turned the AEC tab on
They've bern censored. The same thing has happened to everyone. Spotify says if you have greyed songs and/or playlists they are involved in licensing disputes, but that is a half truth. I'm sure they are with some artists, but that also indicates censuring of your content. Welcome to 1984 in 2019.
