HI, I'm trying to configure the style of pop-up boxes in ArcGIS Experience Builder. I've created a web map in Map Viewer classic and configured the pop-up boxes to be a custom attribute display based on some html code which I have imported. However when I load the map into ArcGIS Experience Builder, some of the styling of the pop-ups is lost, and I cannot seem to find a way to alter the background colour (black) of the pop-ups in Experience Buulder.
