Payment - Adobe suddenly won't accept my credit cards

Sorry if this isn’t the right community to ask, but I haven’t been able to find a clear answer anywhere.

For many years, I’ve had access to an NGO license through TechSoup, similar to student licenses, and as far as I know, I’m still eligible for it.

Previously, I’ve had no issues using my credit cards to pay for Adobe Creative Cloud. However, now none of my four credit cards are accepted by Adobe. All of them work perfectly fine for other online purchases, and my bank has confirmed there are no issues with the cards.

I did manage to complete a payment via PayPal, but I would prefer to pay directly with my Visa or Mastercard.

One thing I find unusual is that when entering my card details, I’m not asked for the CVC code—only the cardholder’s name, card number, and expiration date.

I’ve already contacted Adobe support, but unfortunately we had difficulty understanding each other due to the supports heavy accent and poor English skills, and the chatbot hasn’t been helpful as it just repeats the same responses.

Has anyone experienced something similar or knows what might be causing this? Any advice would be greatly appreciated.
