Are you cleaning the crate thouroughly with something to erase the smell? Also maybe you need to give her more time to go. My dogs will pee right away and stroll around forever before they poop. I spend many of the middle of the nights sitting on the front porch waiting for them to do something. I also had a problem withone of my rescues going in her crate AFTER she learned no too. sahe had a relapse. So I read somewhere to not have ANYTHING with them in the crate , not even a blanket . So I took everything out and she soon was back on track not going in the crate.
