@Sire-DZG Actually, you are misinformed as to what "synchronization" is in Opera. Opera is a combination of "back-up" and "synchronization". Bookmarks are synchronized across all devices. Passwords, etc may be also. Speed-dials are NOT. They are only backed up to the server. If you want a particular speed-dial on all of your devices you have to copy and paste it from one device to another. As the data is displayed right now it is impossible to determine if any other synchronized features are encountering the same issue.

@badwolfpro1 Was Sync enabled on the other laptop? There is a backup?

@NiceHuman Unfortunately I couldn't find a way. I'm trying to get used to it but it still bugs me. Hope someone pops up with a solution.

I have just stopped opera, loaded the file from my original laptop SSD drive, as the adaptor has just arrived (rather than the backup I used, made the day the laptop expired), restarted and checked the bookmarks again. Now, under 'other bookmarks' is a folder with my old laptop id which has the speed dial entries in. Must be a problem with the backup, as the one on the drive seems to work. Thanks for your help.
