thank you , i followed the same steps you have mentioned. My PC was in sync with my phone and it was listed also. But the error I mentioned previously didn’t keep my PC in sync (it neither kept my phone in sync) though the desktop version shows the synced history and the devices connected.
It displays only the old bookmarks not the new ones.
and today just to test how well the brave works I manually synced once again -> uninstalled it-> reinstalled Brave from playstore and tried to sync .
None of ,my bookmarks were restored!!! I dont think I can use Brave anymore.
Please let me know if you need anymore detail.
