I'm attempting to use the new $pixel profile in a pop-up for a Tiled Imagery Layer in a Web Map. I have a fields list set up and I can see that there are pixel values for the areas in my tiled imagery layer. However, when I attempt to use an arcade expression to access the pixel value, it says there is no value.
Fields List in Pop-up:
Arcade Expression: (Console shows default message, no pixel value)
