Sync isn't working at all in Windows 11

[FahimFBA]

Description

For the past 3 years, Brave is my default browser in my phones, tabs, desktops and laptops. I haven't faced this type of issue for quite a long time. After installing a fresh Windows11 and installing Brave, I added my previous sync chain to the browser, and I clicked on Sync everything, but unfortunately the sync isn't working at all. I have waited more than 3 hours, and restarted my PC, cleaned the junk using Bleachbit and so on, but nothing resolved the issue. I checked the Sync everything and later Customize Sync but nothing works at all. Even though I am selecting Customize sync and selecting all of them, after refreshing, I am finding out that all of the checkboxes are disabled and that happened automatically!

Steps to Reproduce

1. Download brave from the official site
2. Install
3. Add the sync chain

Actual result:

Expected result:

The sync should have started and been completed within some time.

Reproduces how often:

Every time in my case.

• Brave 1.32.115-1 (unintalled now)
• Tablet with LineageOS (installed through Play Store):
  • Brave 1.33.106, Chromium 96.0.4664.110

Manjaro shows the same behavior as above (Listing no devices and unticking every sync setting)
Android shows "LOADING DEVICES..."

My phone is the only device still on the sync chain.
Removed other no longer existing devices in the process of trying to make it work.

I experienced the same problem on windows 11 and leaving then rejoining the sync chain fixed the problem for me.

The issue has also been resolved for me after trying some days. I am closing the issue for now.
