HomePods won't sync after upgrading to Sequoia from Senoma.

Hello,

After upgrading to Sequoia my 3 HomePod Mini's won't sync when playing through Apple Music. It may last a few minutes then 2 will just stop! I get errors on my Mac saying it can't connect to each HomePod Mini.

I had no problems with Senoma.

I have deleted each Homepod & set them up again as advised online but, still same problem. I also updated their firmware.

Any ideas why this is?

Kind Regards,

Simon.
