I am holding onto my copy of Affinity 2 and never letting go... mainly because Canva never bothered porting the third version to iPad and the whole point of me buying Affinity was that I could open the same project on iPad and Windows.
It’s not a simple port, is it? The iPad apps have significantly different UI and a more iPadOS-ish UX, and their release has always lagged (though, ironically, Affinity started out as an iPad project within Serif; the hardware wasn’t ready so they pivoted to the Mac, but things like canvas rotation were still tested first on the iPad for feasibility)
