Did you manage to find a solution?

I have encountered something worse, all of my bookmarks were removed simply because I logged out of my account and logged in again. And nobody is fixing this bug for me.

Same issue here, the sync doesn't work, its extremely frustrating and makes me want to switch to another app.
