Sync chain created but not working


I’ve created a Brave sync chain so my desktop bookmarks sync to the Brave browser on my android phone, but data is not syncing. I chose “sync” on my phone, copied and pasted the text into the correct sync-password-field on my desktop browser (which has all my bookmarks), and got a confirmation that it was correct. Under the “sync” menu on both devices, both devices are listed. I have it set to sync everything on both devices, but it’s been over two weeks, and nothing is syncing. I’m at my wit’s end. Can someone please advise? I would be most grateful!
