Fix the performance and stability issues that make what could be an wonderful design app into an unusable disappointment.
The stuttering when drawing or panning the screen, the freezes, the crashes all erode what could be a wonderful way to design vector graphics on the iPad. I LOVE some of the UX details such as how when you delete a node it matches the existing curve as close as possible (I wish this feature was in the desktop version), or the smoothness of the drawing tools (at least until the become horribly laggy).
Sadly, Illustrator on the iPad sits there unused, only opened briefly when a new update is pushed in the hope that it actually fixes the performance and stability issues. Guess I'll go back to working in Affinity Designer on the iPad while I wait for Adobe to stop playing around with AI nonsense and actually get back to making software.
