I’m not sure what you mean. Perhaps if I explain my import workflow it might give a pointer to where I’m going wrong.
I attach the SD card and my portable hard drive to the iPad and copy the files from the card to a folder called photos in my iCloud Drive This folder has sub- folders related to the date of the images
I then copy those files to my portable hard drive as my originals back up copy
Disconnect the hard drive and card
I use open from iCloud to load the image I want to edit and let Affinity photo save it after I’ve finished by going back to the load screen. I can still see the unedited RAW files in my photos folder in iCloud Drive but if I reload from that location Affinity photos just loads the edited version
This is happening with all my edited images
Edit : OK scratch that. I seem to have rectified the problem. I’ve not actually been saving the images, I thought Affinity did that automatically. Once I physically save them I’m able to load the unedited RAWs
