HomePod repeating opening song of playlist

[mac98aop]

Hi folks

Ever since latest HomePod update, all our HomePods (mini, OG) repeat the first song of any and all of our playlists before then continuing with the next, in Apple Music.

All other macOS and iOS devices play the same playlists just fine.

And HomePods play artist albums just fine.

It's only playlists on HomePod. 

I've turned them off/on again but it's not fixed and it's really rather annoying (yes, albeit only a very first world problem).

Any ideas please?

Thanks, Adam
