@leocg Hi Leocg, as previously mentioned, unfortunately I do not have such setting options on my Opera version. I know you usually find the setting in the Advanced User Interface Settings, but mine doesn’t seem to have it. As a result I looked online for a solution and tried changing my Local State field to a different country “CA” as I know “US” doesn’t have the current support for chromecast.
Let me know your thoughts, cheers
