I cannot add my refrigerator to the app. I have a refrigerator with smart diagnosis but no wifi connection or tag on, so I have to add it manually. Except when the app gets to the question in the add device feature on if my device has smart diagnosis, and I press yes, there's a brief flash of what looks like a blue washer in the center of my phone screen, and nothing happens. It does not progress. There is no further instruction, just the question. I can't use smart diagnosis without adding it.
