Yea, once it is on a system, it runs pretty well from what I saw. There are just a lot of steps to get it to emulate, you can't just simply run it through wine.
Canva is notorious for eventually turning everything they touch into subscription services. They altered the licensing agreement and this is why there is now Affinity, and Affinity V2 applications i believe. From what I understand Affinity apps should be safe with their lifetime licensing, but they wont develop it further. V2 I am fairly certain they can turn that into a subscription service legally due to the license changes, and it will be the one they continue development on.
