@leocg as stated, I logged in via my Google account.. This is my first ever Opera account sign-in.
It's now a moot issue. While I never entered a passphrase, my bookmarks appeared in both PC's Opera browser. I see this is a repeated issue for users and Opera needs to fix a clearly screwed up system.
Also, there needs to be a way to add the speed dial icons to the second PC. Having them in the bookmarks just makes access an unnecessarily multi-step task.
Also. Opera is the only browser that results in 100% CPU when opening!
Some web forms don't work in Opera and I have to use Edge or Chrome!
After several years of usage, I'm considering dumping it.
