Also got the email, IOS (w/auto updates on), app store just said "open" until I selected the app in the store then was able to "update". Wish this had been there when I got my car and immediately needed service, which was almost impossible to contact at the time. Response time from app remains to be seen, though I hope I don't need this feature anytime soon.
In any case, while this should have been there previously, it is a very, very welcome enhancement.
