Data for past seasons cannot be added/updated to the profile retrospectively.
As of October 1, only ski passes for the current season, i.e., ski days between October 1 and September 30, can be added to the profile. Updates are also only possible for ski days within this defined season.
If a ski pass is used repeatedly by recharging it (e.g., Carinthian ski pass), we recommend adding it to your profile again each season using the card number (called the chip ID). The NFC function is very well suited for this.
