I am trying to determine what I can set up for a layer in Pro that will be applicable in ArcGIS Online, in general and also with regards specifically to pop-ups. I have determined that symbology will save when publishing to ArcGIS Online, but for pop-ups it seems the only thing that saves is the display on/off checked items and not the ordering or the title and caption. Is this is case or am I doing something wrong? I have not been able to find any documentation that addresses this specifically, or a detailed run-down of what will "stick" and what will be "dumped" from Pro to Online.
