After significant research, trial and error, and contacts to ESRI, it would appear as if the web applications created with web app builder do not print to scale. The reason for this is WGS 84 Aux Sphere projection used by the basemap is designed to preserve direction and shape but distorts distance and area. For some of our operations we need to be able to print to a specific scale and currently cannot do so. Has anyone else run across this issue, and have you found a solution that works for you?
Thank you,
