How can I view the whole screen for Azumio Smart Scale results?

Earlier versions of Argus fit all the information and graph into a single view that fit within my iPhone X screen. The current version has scaled up that view, such that I only see about 1/3, at the bottom-left of the view, and apparently has no way to scale it down to fit the screen and no means of scrolling the content vertically or horizontally, so I get no access to the buttons for anything but “1 month”. The weight is cut off after the first digit and the graph is cut off at just after “20”. BMI and Water weight are showing, but the 2nd column of data is cut off just 1 to 1-1/2 characters into it.
