Adobe rejects my payment before contacting my bank (Turkey)

Hello everyone,
I'm trying to subscribe to Adobe Firefly Pro Plus, but I can't complete the payment.
The error I receive is:
"Your payment couldn't be processed. Please check your payment details. If the problem persists, try another payment method or contact your bank."
The problem is that my bank confirms they never receive any payment authorization request from Adobe.
Here is what I have already checked:
My credit card information is correct.
It is a valid İş Bankası (Türkiye İş Bankası) Visa credit card.
International online payments are enabled.
I have successfully used this card internationally before.
I entered all card details manually (not autofill).
I tried different browsers and devices.
My bank confirmed there is no declined transaction on their side.
It seems that Adobe rejects my card before the payment request reaches the bank.
Has anyone experienced the same issue, especially from Turkey? Is there any solution or something I should check?
Thank you!
