With Sync, you can keep your Vivaldi browser data synchronized across multiple devices. Meaning, the Bookmarks, Notes, Passwords, etc. you add to Vivaldi, for example, on your laptop can easily be accessed on your mobile device and vice versa.

If for some reason the data doesn’t seem to be synchronized, first check Sync Settings and if everything looks as expected there, type vivaldi://sync in the Address Field and press Enter to check for any errors on that page and see if you can figure out the cause from there. If you need assistance, don’t hesitate to ask for help on the Vivaldi Forum.
