Hello,
I am able to update renderer of a FeatureLayer so it is can use custom SVG icons, you can see in codepen, but I am not able to do the same for a sublayer of a MapImageLayer. Although sublayer is able to display PNG icons using renderer but SVGs don't work there, codepen link is here. I just spend my whole day on this issue but not able to figure it out. Any help or guidance in this will be highly appreciated.
Thanks,
Naveed
