I have an iPhone 11 and Lightroom won't import photos from Camera Roll. I've noticved that import from "All Photos" is grayed out, yet I have it allowed in my iPhone "Photos" settings? Any help would be great.
In iOS Settings > Privacy > Photos > Lightroom, ensure All Photos is enabled (not Selected Photos or None).
In iOS Settings > Privacy > Files and Folders, change Lightroom to Off and then back On. Some users report this helps in cases where one is trying to import from an attached storage device (SD card, camera, other iOS device, etc)
