What type of players are you adding to the group. You mention chromecast but what are the others?

[PaoloVittori]

I've 6 google smart speaker:

1 NEST HUB
4 MINI
1 NEST AUDIO

They have been added to music assistant via the Chromecast provider.
I tryed both 'Chromecast' and 'Home Assistant MediaPlayer' (not at the same time) providers and joined the relative entity_id with same result.

Tryed both 'Enable experimental sendspin mode' enabled and disabled but nothing change.

Ordinarily you would group these in the google home app. I will try and reproduce this but I couldn’t with a chromecast and Sonos speaker.
