When I click Cast..., the “Cast Tab” popup shows Looking for devices... for a couple of seconds and then settles on “No devices found”. Clicking it takes me to a Google KB article that doesn’t help at all; I have two Chromecasts on my network and both show up normally on the Netflix app on my iPad.
Some additional info:
- I am running Opera 62.0.3331.72 over Windows 10 v1809 build 17763.615
- I am absolutely, 100% sure I am connected to the same network as the Chromecast
- My network does not have AP isolation, and my computer sees it as a private network
- My antivirus is Bitdefender Free 184.108.40.206
