Hi @Odiedog2.
Welcome to the Sonos community and thanks for reaching out to us.
Allow me to share with you the guide on using Airplay 2 feature from an apple product. Here on the other hand is the guide on controlling Sonos via direct play using the native app of the Music services and as well as what music services support direct control.
With that being said, I would like to clarify that Airplay2 is an Apple ONLY feature that allows you to control Airplay capable devices regardless if it is a Sonos device or not and music streaming via direct control or casting is a feature available on any device that supports streaming and/or casting as well as the music services that allows the feature as well. Airplay 2 is an Apple feature and casting and/or streaming is a music service feature which applies to both Apple, Android, and Windows platform..
I hope this brings a little clarification on your concern.
Please let me know if you still have further questions or concerns.
Thanks,
