Reproduces how often:
All time

Brave Version(See the About Brave page in the main menu):

Type of devices currently running on the Sync chain in question:
Windows 10 Desktop

Additional Information:

That’s your problem. Sync code changes daily. To quote myself from other posts:

Sync code has been 25 words for a while now. If yours is 24 words, it means yours is far outdated. If yours is 25 words, it’s important to note that the 25 word code actually changes daily, so you can’t keep it as a backup.

Good news is just the 25th word is what changes, at least for now. So typically for someone like you, can just add or replace the 25th word. One of the devs created a site where you can check the 25th word, which you just need to add/replace to the end of your phrase. Link to site is

As to sync, keep in mind their warning.

Warning: Brave does not officially support using the Sync code as a backup and you should not rely on this continuing to work in to the future. Use the export functionality in bookmarks and the password manager instead.

This is a big problem. You can export and import bookmarks from the desktop version but you can’t from the mobile. There’s no effective way to make a back up from the mobile browser. Hence if the code is expired there goes all your bookmarks and everything. Not very good sync solution or at least give us a backup method if your sync isn’t going to be it.
