I have iCloud sync for bookmarks enabled on my iMac and my iPhone. Yet at some point I ended up with way more bookmarks on my iPhone, I even have some duplicates where I renamed a bookmark on my computer. A lot of them are bookmarks I've cleaned up from my computer based browser but for some reason they're not going away on my iPhone. Is there a way to delete ALL bookmarks on my iPhone or force overwrite them with the cloud bookmark set?
