ipad pro 9.7 wifi 128GB user here
im on ipadOS if that matters,
im having the same issue. i bought affinity photo for ipad to edit raws from my sonya6400,
my current workflow is to upload raws in google drive and make them available offline in ipad gdrive, open in affinity photo and edit,
my additional question is, is it possible to save current raw develop edit without pressing develop yet? when i close the file without pressing develop, it doesnt save in app.
file size per photo is 24mb, 6000x4000. theres not a session when it doesnt lag, im so disappointed, i just bought the app T_T
EDIT: i just offloaded the app, Trying to reinstall again, this timewithout messing with the settings....
or if theres any setting that i can turn on/off to optimize performance (lesser undo, cache), kindly specify.
