There is a bug in iPhone xsec in that the “>” button in the top right corner sometimes appears dimmed as though it is disabled when in fact it is enabled. This is caused by a bug in the software used to create xsec rather than in xsec.
When this button is disabled it is made not visible so that whenever it is visible it is enabled; dimmed or not.
This does not affect Mac xsec or PC xsec.
Not sure where to contact you. Does the app provide cross section properties?

Your comment to the xsec web site on April 26, 2019 has only just come to my notice. I apologize that you received no reply until now. You asked Does the app provide cross section properties? That was almost six months ago. Nevertheless I assume you are still interested and will attempt an answer. The whole purpose of the app is cross-section properties. However the answer depends on what you mean by ‘cross-section properties’. I list some of the properties output described in the jargon I know in the hopes of answering your question:
The ultimate strength bending moment about any axis and for any given axial load.
The yield bending moment about any axis and for any given axial load.
The curvature caused by a given bending moment about any axis and for any given axial load.
The transformed section properties using given modula ratios for each of the component parts. This includes the area, centroid location, and second moment of area about the X and Y axes.
I hope that helps after all this time.
