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?
This. If the battery is warm enough because the ambient temperature is high enough then no pre-conditioning will occur. Where I live it will probably be November before I will see it work again. I am fortunate that I had the update when there was still some cold weather so I could see it work.
