Lenses should utilize the Snapchat camera when taking Snaps
I've been trying to make a lens with the image picker but get a message after I publish it saying "Lenses should utilize the Snapchat camera when taking Snaps.". With my lens, I have tried to put an image from camera roll behind the face of a person with segmentation. Kinda like a green screen. But when I flip the camera it lets you pick any photo from your camera roll which is not what I want. I want the segmentation and image picker to only work when there is a face visible on either camera. How do I do this?
