We have had new cookies created so we can now monitor last touch. First touch is working as it should and always has - this is a static field. The last touch has been created so it is overwritten each time the UTM value is populated. I've gone to create the last touch hidden values on our web forms but after doing some tests, no last touch values are being pulled through. I'm not very clued up on cookies and the development side of things so any advice would be great as to where to go next / what I'm missing?
