Sync stops working randomly and cannot be restarted without new sync chain. (Bookmarks no longer syncing, send to device no longer working reliably either.)

@Alexey @kamil If there is no update on work being done, can you let us know? Would prefer not having to keep checking in and bothering you if this issue is low priority or no longer actively being worked on. We understand you’re very busy and doing your best with limited resources. Thanks!

@ntarox,
I can assure you that this is being worked on — I’ve pinged the devs for an update and will reply back (or they will) here when available.

Just adding my +1 that this is a serious issue, especially since i work on 3 different devices and have no working sync. It’s annoying and really making me consider switching to a different browser all over again.

Cmon Brave! We’ve been waiting for the fix, now I’m also stuck on three different devices not syncing.

I have bookmarks saved on each device which differ slightly to each other due to the length of time that the sync has not been working and me racking up bookmark saves.

How long before a normal fix?

All devices including mobile have a bookmark export function that works very well.
Export from all your devices, sort each by recently modified date, and go over the differences to bring one of them up to date.

from bs4 import BeautifulSoup
from datetime import datetime

# Function to parse and sort Mozilla bookmarks from an HTML file
def sort_mozilla_bookmarks(file_path):
    with open(file_path, 'r', encoding='utf-8') as file:
        # Read the content of the HTML file
        content = file.read()
    
    # Parse the HTML content
    soup = BeautifulSoup(content, 'html.parser')
    
    # Find all the 'A' tags which represent bookmarks
    bookmarks = []
    for link in soup.find_all('a'):
        last_modified = link.get('last_modified')
        if last_modified:
            # Convert last_modified to a datetime object for sorting
            # Mozilla's last_modified is in microseconds since the epoch
            # date = datetime.fromtimestamp(int(last_modified) / 1e6)
            date = datetime.fromtimestamp(int(last_modified))
            bookmarks.append((link.get('href'), link.text, date))
    
    # Sort bookmarks by the last modified date
    bookmarks.sort(key=lambda x: x[2], reverse=True)
    
    # Print sorted bookmarks
    for url, title, date in bookmarks:
        print(f"Title: {title}\nURL: {url}\nLast Modified: {date}\n")

# Provide the path to your Mozilla bookmarks HTML file
file_path = 'bookmarks.html'
sort_mozilla_bookmarks(file_path)

Just finished resetting my pc and lost years of things because it decided not to sync for some reason. Only my bookmarks synced even though I had everything checked and whenever I try to unlink and relink it now it just doesn’t do anything. Is there like a server that’s down or something if anyone knows.

What does it say at brave://sync-internals?

89

the type info thing on the right says I have nothing saved when right before resetting i had everything there even the brave on my phone but both of them are somehow gone now via sync only thing that saved was bookmarks some reason

I gave up, deleted my sync chain and created a new one, with “History” disabled in the sync options.

Again it stopped working for me. I thought the new limit would be fine for me for a while. ;-;

"error_message": "There are already 85000 non-deleted objects in store",
        "response_type": "OVER_QUOTA"

Is this still being investigated by the team? I also have the same issue

Same here. With history disabled for syncing, I’m seeing the “historyItems” decrease. I still have an issue on mobile where I get the yellow boxes, but restarting the browser makes it green immediately after. Next time I see it, I will screenshot it.

98

yeah , same i hoped till now , maybe there would have been another solution. but no. and i don’t need the shitty history over the devices, only bookmarks and passwords… but thanks for your suggestion. i went that way , seems to sync now. lets see how long it will last… cheers mate.

New problems started today:
despite brave://sync-internals/ showing OK/all green on all devices and commits to sync apparently running normally HISTORY DOES NOT SYNC across devices. Sigh.
All I see is “GetUpdates Response Received 0 update(s).” on my other devices.

This is with a fresh sync chain created only 2 days ago.

One of our developers gave an update on what we are working on to resolve this issue here:

I was actually just coming here to give everyone this little update. I’ll hit key points, but for anyone wanting to see the entire conversations and info, you’ll want to go to https://github.com/brave/brave-browser/issues/35042

And then a little later:
