I have the same problem. Yest I tried the menu and Settings. Refuses to work. Most frustrating.

Can't sign in to OperaOpera for Windows
Opera for Windows 10. The "head & sholders" on the far right of the menu bar shows a white cross in a red circle. When I click on it to sign in (in order to synchronise my settings with Opera on my second computer and my phone), nothing happens. Tried re-installing the latest version of Opera, but to no avail. I've tried searching here and elsewhere and am amazed that I found nothing useful. Frustrating.
