SONOS grouping issues

Hi,

new to Roon (and Sonos, which was a result of going down the Roon path):

I have a Stereo Pair and some Stand-Alone Ones and am able to group them both “via Sonos Streaming” and “via Airplay”.

Issue seen is that having the Group “via Sonos” is having issues depending on which Room played first:
When Stereo Play was playing and I add Standalone, the Standalone is not playing (but UI displaying it is)
When starting with Standalone, adding Stereo-Room into the group, only one of the devices is playing.

When doing “Roon over Airplay”, everything works as expected. But thats not what I want, I could do that natively with my iPhone.

Q: is this expected behavior or am i missing some important setting?
