@Leigh:
Hello,
in the meantime I had also wrote to Serif and I told them my order number, but I am still waiting for the necessary bill!
Actually, I would be interested to buy "Affinity Photo" for Windows as soon as there is a final version. But if it is so cumbersome to get a reasonable, legal bill from your company, I have to think about it ...
For other companies, where I bought software so far, this worked without problems: After the purchase you either get a corresponding download link or even the invoice as an e-mail attachment.
Why is this not possible with your company?
Meanwhile, I am very annoyed and certainly not with my opinion alone!
Best regards
Jörg
