Yes, the problem is solved now (thankfully). Now the only mystery is why I couldn't get the update through the owner account dashboard.
It's a 2019 Fiesta, and I copy/pasted the vin from the dashboard site to the other link, so I didn't mistype it somewhere. Both cars are registered on my account.
I wonder if it did originate from outside the UK (steering wheel is in the right place though!)
Or, maybe it's just one of those glitches. I may contact Ford to see if they can sort it out for the future.
