I noticed today that the hopper area is able to shift back and forth. I felt it when I was adjusting the grind and even without turning the hopper I can shift it back and forth which also seems to move the burr back and forth. Is this expected?

I talked with Niche and it sounds like this is expected since there has to be a little play but as you get farther down the burr it has less effect on the grind. I don't really have a way to tell if there is an issue or not.
