I have saved .rft.xml files from ArcGIS Desktop Symbology workflows and imported them into My Content on ArcGIS Online. However, when working with my maps in ArcGIS online and then going to the Image Display properties for the Image Service I want to render with the template, I do not find a way to add or access the templates I have uploaded. What is really puzzling is that I see a template that I must have made a while back (the 2018HydroImage template seen in the screen grab below), but I have no notion of how it got there. I don't see it in My Contents. Any advice appreciated.
