I have added SSL certificate to my website TvojSajt.com almost month ago, I do have rel=canonical and 301 redirect set up correctly. Your biggest rival (will not name it, but you know who it is) took only a week or so to start indexing and showing in search results https version of my website, whereas Bing still shows old results.
Also, I have changed meta description and title of several pages at similar time, but Bing don't know about that still.
Work on that algorithm, please!
