I just ran into this same issue. I have an iPhone X and a 12.9 inch iPad Pro first GEN. When I use the SD card Lightning adapter to import HEVC files into the iPad Pro they fail. However if I import them into my iPhone X it works. And then I just let everything sync to iCloud from there. I’m not sure why it won’t work on the iPad Pro but this workaround isn’t too bad .
