I hope someone can double check, bu it's a complex use case :
I cannot send music from the deezer app on iOS (iPad +iPhones) via chromecast to my B&O stuff (mkII Essence and mkII A9, so not last gen) with a deezer hifi subscription.
What I can do is send deezer hifi to a chromecast audio (that's why I think the issue is B&O related), and send spotify or any other app audio to my B&O stuff via chromecast.
I can also play deezer hifi directly to the B&O stuff from the B&O app, but that means that I cannot access the personnalized playlists such as deezer flow. I can also Airplay, but that means lower quality and battery drain on my iStuff.
Can anyone try if it's just my setup or if it's global?
