[Designer on iPad file storage]

Hey guys,

I also have the problem with saving files. Offloading app doesn’t help with cleaning storage and making free space in my iPad memory while I’m working on multiple illustrations. Please tell me, if I will delete the App Affinity Designer from my iPad completely will I have to purchase it again in App Store?
