Can't link card to iTunes

For some reason iTunes rejects my maestro debit card, is there a way to fix that or work around?

Daniil I don't think iTunes supports Maestro cards. I suggest you try a Mastercard debit or Digicard (also Mastercard).

Daniil Hi 👋 there,
Indeed Maestro is not on the list of payments accepted (at least in NL):

You can use alternatively PayPal, iDeal or get a virtual Master Card @ Bunq (free if within the plan/limits) or add credit via an Apple gift card.

Hope it works 🍀
Have a great day 🌈
