Hi Aurelien,
My name is Tomas Paez, I manage the SW Licensing Portal and licenses for NXP products.
Expiration date is a default value added by the system, in this case the default period duration for an enablement SW is one year.
Like mentioned in previous activities, this SW works in perpetual mode, so we do not plan to remove or to discontinue the product.
This date will be extended automatically by the system near expiration date.
Let us know if you have any other question.
Regards.
Tomas Paez
