There is a way, but it's not well suited for me. .CR3 is supported on iPad Pro. It’s an app issue. Apparently, one must use the Canon Camera Connect app to connect to the camera via WiFi. I tried it and it works. I uploaded .CR3’s with the Canon app, exported them to the Photos app, and from there I imported them into Lightroom for iPad, which was my objective in the first place. This is a needlessly complicated process. I don’t know who needs to fix this—Apple or Adobe—but it does need fixing, IMO. As things stand, this involved process isn’t of much help to me, as I would like to be shooting with another card while my pics upload to iPad Pro from the previous card. Uploading from the card works with .jpg and .CR2, but not with .CR3’s.
It would also be really neat if Camera Connect could upload from a variety of sources other than cameras. I'm thinking not only a card reader, but my My **bleep** wireless SSD drive.
Perhaps the import process will be streamlined when Photoshop for iPad Pro is released.
