Yes, I know, as I know also that you are not the cause of not being able to solve it; as I surely do appreciate your assistance in trying to do it.
Anyhow, it's a pity that there is no-one of Opera itself who can take up this item: it is clear that there is something wrong in the system between what is saved and what can be accessed through synchronisation, and that is or a bug or a malfunction that the IT services should have a look at.

@trueraho You can't sync with iOS. But when using the "flow feature" you're having at least a half baked synchronization.

You can log into your account by going to: auth.opera.com. But you don't get synchronization work by that either. But if you want to use Aria in your iOS browser it's required to log in.

@jlchamberlain My sync is indeed finally working again!
Thank you very much for the link to the post with the solution!!!

@admin this is another problem worthy of Opera employees attention.

Apparently sync either doesn't work at all, only partially works, or works just fine.

Just had my bookmarks "sync" from my PC to my laptop, and it didn't even sync the bookmarks properly, as only a few of the new ones got popped over to the other device, while still failing to sync the older bookmarks.

How am I supposed to delete all those bookmarks in Trash if I can't even access them?

@simone-brunacci I guess it's an old known bug.

@codewolf2 Theoretically? Disconnect all devices from Sync, reset it, then connect the device that still has the correct data on it first and allow it to update the servers. You may also reset the data on the other devices (before re-enabling Sync on them) to make sure they won't overwrite data on the servers.

There may be ways to do it that are simpler, but that's the obvious one. Make it seem to the server like all the other devices have only just had Opera installed, so that it knows to only Sync to them rather than from them.
