Thanks
@Tom D , great summary to which we could add:
Software Update Issue: Justin Hocevar (IA head of region Asia Pacific) told folks at a recent drive event in Australia and reported elsewhere on this forum that the software issue had been fixed "past tense". So that implies the updated software just needs to be loaded onto the vehicles either at the factory or dealer during PDI which should be a pretty routine activity.
Vehicle Registration Issue: It seems in the UK at least that IA are registering the vehicles themselves rather than the dealers and that they may not be sufficiently prepared for this with the correct DVLA portal access and trained staff to complete the registration process. This "admin oversight" seems plausible in terms of causing a delay to registrations in UK. However, it's strange that no customer vehicles have been registered anywhere in EU or Switzerland either, despite some being delivered to dealers. This implies the problem may be more deep rooted than final registration admin pointing (possibly) to difficulties obtaining Type Approval and/or Certificate of Conformity.
