Posted this problem in Portuguese also in the Brazilian tech support community. Everybody keeps giving responses about licensing (it isn't licensing as I can access the music through the individual albums) or about playlists I have stored on icloud, which it is not, as it involves those playlists suggested by Apple Music. Someone else responded n the Brazilian forum that he has the same issue, but found if he right clicks on the playlist to Show in Apple Music, it opens normally, and if you click on the playlist to play without trying to open it, it also plays. It is only when you try to open the playlist by just clicking on it. The message says the item is not available here. Contacted tech support for Apple Brazil in Portuguese and the guy simply said it is a licensing issue, which means he didn't even bother to read my comment nor did he bother to investigate. I got in touch with tech support in English and the tech was amazing, noted that this might be a possible issue developing in the Brazilian version of Apple Music, but was unable to resolve the problem. We had scheduled a call for today to try more troubleshooting when as mysteriously as the issue began, it disappeared. Everything is now working properly.
