I just wanted to upgrade my current v3 version of little snitch to v4 (during black friday), i tried several times.
But unfortunately i constantly receive an error when i try to pay with my credit card (master card): the transaction was not successful!
After 5 or 6 times i know for sure i did everything right. What can cause this and what now; because before i blink my eyes; black friday is gone and my good deal also.
Please advise me!
