Hi @mikolajek, I don’t think anything changed here.
1st card is free, + GBP 5 delivery costs if one wants a physical one
Virtual spare card is GBP 5 (or GBP 10 for a physical one incl. delivery costs)
Considering that not all users want or need spare cards or virtual cards, it is just fair in my opinion to apply fees for customers who actually use these options instead of cross-subsidizing the costs for card issuing / delivery with income generated by all customers.
If you were actually charged for the 1st card, I would ask the support for a refund. The FAQs clearly state that the 1st virtual card is free: Section “Card --> Are there any charges?”
