It appears that the "Chromecast Integration (beta)" doesn't properly register devices that are running the new "Fuschia OS".
When I noticed some devices weren't visible, then tried a discovery, I got two that showed up as "null [null]" and the device(s) that I see have upgraded to the new OS are not otherwise listed.
I checked the box for the two null devices to get them added--and they were indeed the Fuschia ones. I manually entered the right device name for them and they seem to work otherwise.
Woohoo, right?
Thanks.
