@HealingCross316 Yes, it might have just been a bug. It's working for me now. I was surprised to see many issues with the flow and no solutions, which led me to think it was a known problem that hadn't been addressed. Is anyone else still experiencing this issue with the latest version of Opera?

I also have the same issue. Tested with the Opera Android, Opera Beta, Opera GX (Android) and on Desktop windows 11 Opera One(version: 113.0.5230.62). I'm trying to connect to My Flow from the side panel or from the opera.com/connect and it always fails. I can see this issue on the forum and reddit from 2018/2019 which is crazy that it is still not fixed and people are having issue with this.
I tried disabling adblock, trackers, extensions, log in/ log out. But nothing seems to work.
Is there some fix for this? Is it possible to get it working?
