Hi Philip,
I appreciate your solution but that was no exactly what I was looking for. My question was about how to get an image in a note question to scale to fill the screen of all devices, not the map or image questions. Sorry if my post was not clear to begin.
Though your solution was not my solution, it did give me enough of a clue to dig into survey 123 connect where I noticed that the header note, which scales images as I was hoping to do with other note questions in the form, uses the media::image column to reference the image in the note and that seems to scale things the way I want without using the body::esri:style column. I would add for those who are searching for a similar solution, it is probably worth reducing the size of the image that is included in the media folder to be no wider or taller than your target devices might benefit from.
Thanks again for putting me on the path.
