I have been using Chrome and the sync works there smoothly. I missed Opera and gave it a try.

The only option that is missing is the synchronization. It says that I need to log in on each of my device. It should sync automatically then. I use Windows 10 at work, at home (laptop and desktop), Android 8.0. None of them sync with each other. Is the sync sever down or something? Please help, I would really like to come back to Opera and leave Chrome. I mean it.
