@Suty Many thanks for your assistance, I will contact FastSpring

@Suty Correct, I changed the Apple email private relay on my profile but still I am not receiving the FastSpring email. Is it possible to have FastSpring use my new email for the communication ?
Thanks in advance

Hello, My Premium membership is about to expire and I have to update my payment details. However, I haven't received the email of FastSpring even though I tried several times . Can you please assist ?
