Opera Version:73.0.3856.344
Win 10 (latest)
Site: watchtv.cox.com

I have used the app on my iPad for years; to get same function on a computer one accesses this function via a web site. The website is identical to the Apple app.

After logging on with my ISP , I tried to "watch" a tv channel from my favorites list. Clicking on "watch" did nothing for any channel.

I tried MS Edge, and no problem. I was able to stream channels.

CNN is my test channel; however, in this case I used a number of channels.

I disables the two extensions I have, cleared cookies, did not have VPN on, and turned off privacy protection. Nothing helped.

Any ideas? I have used Opera only since it was first released. This is the first issue I have encountered.
