@uberprutser I have a similar problem...
or had I should say.
While I was on holiday, Opera on my WIndows 10 work computer upgraded to Opera One, therefore logged me out of everything.

First of all I had to reset the password of my Opera account since it kept on telling me it was wrong...

Then I realised that my phone had been kicked out of My Flow.
When trying to reconnect it, I opened My Flow on the side bar on my computer. I could scan the QR code, I get a confirmation code on my phone and the request to follow the steps on the other device, but on the computer I just get logged in to my account.

However, by opening a new tab on my computer, typing in opera.com/connect, I got another QR-code, and that way it worked.
You might want to try that. I am not 100% sure if I did something on my phone that prompted that tip... Maybe through the "other options" at the bottom of the screen (phone).

Good luck!
