Entity info in sketchup for iPad

On Sketchup for iPad, the entity info box does not seem to show the fields available in the “Advanced Attributes” on my Mac. Specifically, I was trying to enter a URL for an image on Dropbox that when activated from the Entity Info dialog, would open that image on the iPad. It works on my Mac.

Does the iPad app not have the extended capabilities that are on the Mac, or is there something I’m missing?
