I had a lot of bookmarks, I sorted them out and deleted them, pressed synchronization, everything seemed to be deleted and left in order, as I wanted. But he left, after a few days, from the account and here again all my bookmarks (there are a billion of them, I filtered them for a week) again with me ???? What is this ? You can't do anything there at all - what is the logic of this synchronization of yours? Everything that was once synchronized will always be like this ????
