Apple Watch not displaying playlists after new UI introduced

[ritave]

I was using Apple Watch for running, and it was working normally previously, both streaming and offline playlists would play.

After the new UI was released lately, it all broke - I can't display the list of playlists when connected to phone and internet. It's just gray placeholder squares.

Offline doesn't work either, when I select the "Downloaded" tag, and I have 5 playlists already downloaded correctly, it's also stuck on grey placeholders, no matter if the watch has internet, or not.
