Photo Library - can't find original file when I try to download or edit
I have my photos on an external drive. I can see the photos in my upload history. They open fine. I have double check to maker sure I can edit and download. However once I close photos and and remove the external drive, the next time i one the files it says "can't find originals" This have happened the last 3 times I have imported photos from my camera. What could be causing this issue and how to do fix it and find my originals?
MacBook Pro 13″, macOS 10.15
