I have been working with the new ArcGIS Images for ArcGIS Online (https://www.esri.com/en-us/arcgis/products/arcgis-image/options/arcgis-online) which are well worth trying out if you haven't already. However, it seems that you cannot use the Print Widget in a WebApp if you have one of these images open in your Web Map. I am trying to export an image from my map, primarily a geotif, but get an unspecified error whenever one of these images is turned on.

Anybody have any suggestions how to get round this, or at least confirfmation that they get the same behaviour?
