I wish I knew this before I spent all of that money... I've barely touched the software at all as I was waiting for my Creative Cloud contract to end before moving my workflow over to Affinity. I bought it on Serif's website, not an app store. I also noticed that they directly sell a Mac package outside of the App Store, so it's not like they couldn't just provide both versions to those who purchase a license...
So I basically paid $150 to edit one image (testing out functionality, etc before purchase). Haven't used it since and now that my CC end date is nearing I apparently can't use the software I paid all of this money for. I guess I should have been reading all of the fine print, but it's pretty standard across the industry to only charge customers once for a piece of software. I've never had to pay twice for software, this just seems greedy.
Super disappointing.
EDIT: I realize that you're not an employee, I just had to vent I guess. Sorry!
