Yet another example of where Lexus really doesn't do digital OR treat customers with respect. Completely disabling an App until an update is done is just not the right way to do things, not sending an email advising an update needed is not the way to do things and as others have posted, linking to the wrong App to load for an update and seemingly no one at planet Lexus actually checking the functionality is not the way to do things.
Lexus had a reputation as a premium brand, not now.
