Turns out it was a scammer 🤯
Asked what e-mail address the digital download would come from, so I (probably stupidly) let them have it, then had an email from a .cz email address asking me to click a link. They said they had purchased the download but my spidey-sense were tingling when nothing came up on the Etsy Dashboard.

Turns out all those years spent working in an IT department served me well 🤣
