I wrote a review on the App Store, saying Affinity Photo only crashes on my iPad Air. Then I got a refund from Apple, so my review has disappeared.
i got a response from a developer asking me to post here so they could address it. Not really my problem now, but I don’t like to ignore people who are well-intentioned. I got one photo developed from RAW, and then nothing ever worked. I tried to develop Canon CR3 compressed RAW files. They’re pretty large, 20MB+.
Apple’s Photos app also crashes occasionally, but if I save a cropped version first, it helps. Maybe it needs an iPad Pro or maximum memory.
