My icloud sync seems to have gone crazy, on both my Mac and my iPhone I have hundreds and hundreds of bookmark folders that are blank (no name, no conents). I assume the sync is duplicating them. I can only seem to erase them one at a time and it takes >30 seconds to erase each one, it would literally take me days to fix. The iPhone can delete them faster but for all I know they are being created at an exponential rate. Any suggestions how to fix this with one swoop?
