I have the same issue.

The problem is still not resolved. Opera has very bad synchronization.

After updating desktop versions, there was a problem with duplicates in synchronization. After restarting Opera, new instances appear in the tabs. Every time you turn Opera on and off, a new computer appears. How to fix it?

They will never fix it, neither will sync errors (duplicate records every time the browser is shut down). it's not a bug, it's the future.

@leocg I have tried it. Does not help. It looks like Opera 89 error. Opera Android - doesn't generate this error.

@leocg How do I do that?

@leocg I was doing it. There is no effect.
