@leocg Solved!
Resetting the browser settings made the "Enable chromecast support" appear again on the configurations and now it shows either the cast option on YouTube videos as on the dropdown menu when right clicking with the mouse in any tab.

Thanks a lot for this beautiful help, comrade!
Have a nice day!

"Now what's missing is:
"Enable chromecast support" from the config menu." a.k.a. settings.

Any thoughts on how to fix it, comrade?
Thanks in advance!

Aloha!

All of a sudden the cast option from my Opera GX is gone. It has always worked out fine.
Now what's missing is:

• "Cast" option on the right clicking menu on anypages;
• Youtube/Twitch cast icon;
• "Enable chromecast support" from the config menu.

My Spotify desktop on the very same computer shows the Chromecast on its menu an can cast perfectly to it.
All my other devices on the same network can cast just fine to the Chromecast.

Does anyone know how to fix it, please?
I have made some researches on the forum but haven't find one yet.

Thanks in advance!
