@Ondřej-Šutera Thank you. I have received the email, but my payment has not arrived yet, which may require me to wait for a while. Thanks again for your help

Hello, I have the same problem,I found that after purchasing the membership, my API still cannot be used, and I was prompted that the API is invalid, because I found that I purchased the wrong API Professional version, I need to refund and then buy the API Professional version I need, thank you
