Hi @anasyrma, check if "opera://settings/content/protectedContent" is enabled and if not enable it, and see if this helps.

If it doesn't, try to launch the Opera with the switch as shown below (changing user agent string - add it at the end of the shortcut you use to run it):
"\path\to\launcher.exe" --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.85 Safari/537.36"

If it still changes nothing, you can check one of the other tips mentioned here.
