Xperia 10 II license costs


there was a note about reduced price of 30€ for license of Xperia 10 II in last [release notes] Kvarken 4.1.0.
Now I have bought a used Xperia 10 II on ebay and want to buy a license, but it shows the full price of 50€ in store. Can I get the discount? Is there a voucher necessary?
I’m sailing since years, from original Jolla phone to C, over Xperia X, now to 10 II. So it would be included as customer.

Best Regards

It was a temporary offer. You used to get the discounted price when you logged in but I don’t get it anymore.
