Browser-based Apple Music won't allow login after Sonoma update

I can't load the apple music app because my company has my computer locked down so I can't login to apple.

However, I've been using music.apple.com in my browser to get around it without any issues, but with the Sonoma upgrade, I can no longer even sign in to music.apple.com. I've tried both with password and passkey on both Chrome & Edge.

It doesn't give me any errors, I just remain signed out of apple music. There's a red bar across the bottom of the page encouraging me to "Try it now," but when I click the button, it says I'm already a subscriber, which means it knows who I am, so I must be logged in.

Any fixes for browser-based playback?
