@ROCKKER-55 I may try to make them answer my questions, specially when that answer may be important.
If you think that I'm not helping, you can just wait to see if someone else shows up with a possible solution.
So after getting rid of opera following my last post, I read about Opera 60 and the QR code sync and thought maybe they had fixed the issue. So I reinstalled and signed up for new opera account.
sync.opera.com and the devices still shows open tabs between desktop and mobile devices, but not history.
The QR code thing is useless. I go to opera.com/connect on the desktop, scan the QR code with my phone, and the numbers don't match. After that, it only pulls up another QR code on my phone which it wants to me to scan. Um, I can't scan QR codes with my desktop. So the only option is to log in to an account.
So basically "history sync" is fake functionality. I guess it falls into the "fool me twice" category so shame on me.
Goiodbye Opera. For good this time.
