[Importing sharing photos into affinity from external hdd (iOS 13 )]

iOS 13 enables access to external hdd  such as usb stick and ssd .i use an iPad Pro 12.9 (usb 3 camera connection kit with usb 3 hub and lightning to usb cable. ).  I can copy files from a card reader to an ssd  or a usb stick

i’ve settled on an m.2 250 gb  on a usb 3 adapter 

i can view the photos in files app but not import them in my official affinity software

which makes me regret to have bought the app

especially since I can import those files /share them into darkroom...

 

anyone has a workaround ?Thanks
