Car not talking to my account

[X100]

I recently tried to update the satnav maps over-the-air but my RC F does not recognise my "MyLexus" account, so it won't work.

Apparently, there have been a number of issues with the car not "talking" to owners' accounts, even though the dealer has set this up in the car, at the point of collection.

My local dealer is waiting for someone from H.O. to get back to him about this.  Given that this seems to be a known issue (not just with F-cars, I suspect) I am disappointed that a solution has not been immediately forthcoming.

This is not a reflection on the local dealership, which has been good.

Has anyone here experienced this problem and, if so, do you recall how it was resolved?

Thank you!

P.S. We are entitled to two OTA map updates a year and whilst I normally use TomTom, through CarPlay, I would still like to have the car as up-to-date as possible, for those times when I leave my phone behind.  I also like the reassuring subtle beeps when cameras are near!  (My car is a 2021 model).
