Description of the issue:
I have three divices in a Sync chain: 2 windows computers and an Android smartphone.
My bookmarks duplicate when I start up the second computer (last in the sync chain.
How can this issue be reproduced?
take two windows computers and an android phone, install brave on all three
import bookmarks in one of the computers
sync the three in one sync chain
Expected result:
Erratic behavior in sync resulta when starting a windows computer
I think I found the solution for this problem myself. I think it was caused because I imported bookmarks on both W10 computers from Chrome, which were already synchronized in Chrome. So actually, both installed versions already had the same list of bookmarks before they were synchronized. Amazingly, the Android installation of Brave had no problem with the bookmarks.
To solve the issue, I ended the sync between all devices en uninstalled both W10 Brave installations. Then I re-installed Brave on both computers, without importing any bookmarks. Only then I set up a new Sync between the devices starting from my Android phone. Alle bookmarks that were saved on the Android version of Brave were correctly synced to the W10 computer versions! So now it seems to works alright and what is even better: the sync process is much faster!
I would suggest that you note users to this way of working in the user-guidance during installing Brave, as users are urged to import bookmarks with every new installation. You should tell users them that if they intend to sync, they should avoid importing duplicate bookmark lists
Still, one lesser problems remains: the bookmarks and folders in the mail bookmark menu are stable now, but within the folders, bookmarks are reordered and also website icons disappear and reappear with each time Brave or the computer is restarted. This is much less of a problem, but still it is a bit anoying and unwanted behavior.
