YouTube Music won't play

[FTLego]

The issue is on my Samsung TV UN43MU6100.
Software version: T-KTMUABC-1290.3 (up to date).
YouTube app version: web_20210913_08_RC00.

I reset the app through YouTube settings to see if it would help. Same issue.
Factory reset the TV. Same issue.

Issue:
Any "YouTube Music playlist" or "My Mix" or any channel that has " - topic" as suffix won't play. It shows the cover of the song with a buffering logo for a few seconds, then the error.
Error: Something went wrong. Unknown Audio Playback Error Playback ID: 7Z5Jc_UVySu3dZwf

ID changes depending on the video/song, obviously.

UPDATE 1:
Software version: T-KTMUABC-1300.3 got rid of these issues

UPDATE 2:
Same software version but these issues are back, could be because of an update from youtube app. Not sure.

I don't think that's the case with this issue. It's all over the world apparently.

There is a new Samsung TV update. Version 1300. It made YouTube app worse. When I click on a YouTube music that wasn't working it still doesn't work and then when I click on a regular YouTube video it only shows the thumbnail of the video and then audio. No visual. I have to unplug the TV from the power to reset it for YouTube to work properly again. Yikes. Not going to go through the YouTube Music section anymore.

That was exactly my problem as well with version 1300.

I don't know about you guys, but "Software version: T-KTMUABC-1300.3" did it for me. Any music-related issues I had with it, it's gone.

Thanks, SamsungStephanie, for passing it along to the engineering team.

Well, I'm sad to say that the current version is having all these issues back again.

The same issue with @FTLego happened to me.

The Youtube app worked well with the version T-KTMUABC-1300.3, but it started to crash again a few days later and is still not playing any music.

Same here.  Worked the other day, now it is back to the same exact failures.

Hey guys, same issue here with my UN55MU6100, and I'm from Argentina, so as other user suggested, this is a global problem.
Please Samsung do something!
I already lost the count on how many times I've "sent the feedback" to YouTube, as the error message suggest everytime it appears.
