For some reason my phone isn't displaying any of my Google assistants or chromcast devices. I can ping them from my phone and they are all on the same wifi but they do not display.
For exapmle, no devices display when I try to cast Spotify to a hub or home speaker. If I ask Google to play music from my phone, the device shows up and shows Spotify is casting to it. But once I stop, the device is gone again.
