Reply no 1: When I open my Cloud from Affinity, I have a few options to select, like iCloud Drive, On My iPad and Drive, as source of locations as shown in the attached file below. When select Drive, all the photos appear as Thumbnails but not showing the photos and I do not see the photos are they are. They would only show up after I have edited them on Affinity and save them back on Drive again.
Reply no 2: I have tried your method before, it worked but then it is a very tedious way of doing it. Where as if there is already a photo on the edited page and try to drag and drop another one onto the existing one, then the photo will fit in automatically. I will not have to resize it like you mentioned.
