Brave sync shyting the bed

Hi so ive recently reinstalled my windows and everything on it dverything else is fine beside brave’s god damn sync, it syncs the bookmarks and thats it and when i click leave sync chain it atill stays there

Brave Version:v173.105

Like all i see in sync-internals on browser now is “initial getupdates due to newly_supported_datatype” like ???

Okay so i downgraded to v1.74.46 and it instantly worked

@Marcellhvh,
Are you using the Release build of the browser? I ask because that version is not an official release version of the browser. The latest release build is v1.73.105.

I am having the exact same issue as Marcellhvh, how can I fix this? Only bookmarks synching and nothing else.

I just downloaded from brave.com but now i got the latest stable build from github

Go to the bravesoftware github and get the latest “release” version

What did you do different? I just tried v1.74.46 and it did not work.

Then try going an even lower version? Idk i think my fix was just pure luck

I am having the same issue. Just clean installed windows, Installed brave (Version 1.73.105 Chromium: 131.0.6778.265) in hopes that all my data can be synced back.

But only bookmarks synced… I reinstalled Brave, and again - only bookmarks synced.

Obviously I also backed up all AppData before, but that these days is useless if you want to restore the previous browser state since all passwords, cookies are DPAPI encrypted, etc.

There is also constantly a spam of this going on:

Same. Just tried - 1.74.46 version and only bookmarks are synced on desktop Brave version.

It also seems to only upload local browser history (7) instead of downloading from the common synced ones.

10h later and nothing has changed for me.

Also, people are having the same issue here, but no solution:

EDIT:

18 hours later sync finally worked… Everything else is synced, as you see. Not just bookmarks.
