Unfortunately, it looks like your webform photos did not get uploaded successfully. That being said, mobile devices present a more constrained spacing environment; at this time there are not plans to address column widths for single choice grids.
Hi I'm wondering if there's anything that can be done about a discrepancy between the preview view and the live view of a survey. While in preview, the Single Choice Grid looks fine. But once it gets published, the row height gets truncated and you are now unable to read it fully.
I'm trying to reproduce the offset you are seeing in the single-choice grid's questions and am not. Could you share the specific wording of the questions? You can e-mail me at jtedrick AT Esri.com
