Another issue. (I'm having a problem with the receipt not sending, which I just posted about.) So I manually went in and marked it as complete and had it send the receipt and download link.
The download file is just under 40 megabytes. The file that actually downloads is only 4k and does not work, although it does have the correct file name.
Is there a way to fix this? It happens every time. I have done multiple tests.
