2023 Ioniq 5 AWD LTD battery preconditioning not functioning

So I have read all the tutorials and watched all the videos several times and can not get the battery preconditioning to function. I saw that one of the video posters on YouTube, Wrenching Fool, showed that Hyundai admits there were cars which were given bad software, but there was never any public acknowledgement(TSB), just the document issued to dealers.
The question is if Hyundai doesn't acknowledge there's a problem, why would my dealership try to fixt it. They have repeatedly told me "Hyundai says you're up to date" when the problem as described in the video, is that the latest fix(event 913) has to be applied in sequence after the previous fix(event 892) or you have a problem. Any thoughts on next steps?

What was the outside temperature and battery modules temperature?
Having watched all the videos I noted the temperature was 48F- the battery was cold, the destination was an EA DC fast charging station, chosen from the native nav system. The distance to it was under 30 miles, and 30 minutes, there was 38% state of charge. by every videos "requirements" it should have worked.
I want to thank everyone for their advice. I will probably give in and buy a OBD reader and set it up with my phone. I have followed the advice of Ioniq Guy and Cars Made Simple when trying to activate the battery preconditioning and the fist hint that it's not working is there has never been the little pop up message telling that me that "Battery conditioning activated for optimal DC charging". I tried selecting DC fast chargers near me, more than 30 miles away, more than 30 miles away with less than 30 miles of range, all in temps below 45F. I susepect as I noted above that the updates were installed out of sequence and without some more informed testing, it wont be clear. Next step will be to get in line at the dealer service department. But, sadly, in my expereince these guys will try to perform an oil change.
