People are reporting in the big thread that they had this update done and they're still getting the code. Either the newest update still isn't working, they have another problem, or the shop might have haphazardly just done the old software wiry the "new" procedure.
I got this update done today, no cost, and will report back in. My invoice clearly states they did the 21-022-14 flash. So far so good.
