@flic-l Yes I'm getting the same thing, it turns on my TV via Chromecast, opens the YouTube app, but just shows the YouTube logo and that's all it does! Would love a fix for this?

Was thinking of getting a hub but not interested if it does not work. I have the same issue and any other chrome cast function just does not work. I have 2 phones and one works perfectly fine when the other one doesn't so it just seems to be a software issue or it could be not having a certain permission on my phone. But I have allowed everything I can think of and there should be more information on what permissions I need to enable. The fact that this is a problem and nobody has been able to get a fix for months makes me wonder if this will ever get fixed.

Bump! The Inability of the LR Hub to see Chromecast Audio groups on my LAN means my flics are pretty useless for controlling audio. Is there a technical reason that this is not the case?
