My Apple Music Playlists are empty on my MacBook Pro. I have Sync Library on, and can see the full playlists on other devices. Can someone help?

The same thing is happening to my music, But I already had many playlist, so I was unaware of the issue, because, there are songs on my playlists, but I was adding a song that was included on a playlist and that is when It hit me, for the most efforts to add a single or a group of songs to any given playlist was impossible from Mac, but the iPhone had all the songs including those that I intentionally duplicate, this seems like some credential error or an invalid key, logging in again seems like the logical thing to do, I about to try your solution, Ive noticed that Mac and iOS have very different ways to access some validations, not always works, across various components that depend on iCloud. Thanks for your solution, be back in a minute or so! hopefully 😅

Did't work for me, Maybe I have to log out from everywhere and login back, I may try tomorrow, maybe I get back to Spotify, I don't Know, everything is so complicated!!!! Im about to trow away all the computers, iPhones, AppleTVs, cables, adaptors, and a buch of useless things, I bought and trow my self to the cliff, from this day forward, I let IA to rule everything, I had my chance. 🥺
