Google speaker group cast is not talking to me

I had announcements for media player to broadcast to a group of google speakers . Was working fin for months. Now it goes ping and says nothing,
Has something changed in Google or Home Assistant.

The only change I see are all my speakers are in twice for home assistant due to Media Assistant.

I have now gone to various routines and added in three different announcements to different speakers with a three second delay to get it working again.

Has anyone else had this problem? Does anyone know how to fix it or what I could look at.

Getting the same, have the pop and nothing else,



Tried switching to text to speech with no change

Also having this and trying to figure out how to get it working
