I'm using Portal for ArcGIS (10.5) to create a Web AppBuilder application for printing. I created custom printing layouts and published as service. One layout is 8.5''x11'' (Layout 1) and the other is 12''x15.52'' (Layout 2).
The symbols in the legend of Layout 1 appear fine, but the symbols in the legend of Layout 2 do not appear correctly. See examples below. Does anyone know what might be causing this issue?
