How to add color, gradient and other effects on a Fresco document in Illustrator

[Jacob22237142n07j]

Hello.

I am using Fresco and illustrator on Windows. When I send a Vector drawing from Fresco to Illustrator I am unable to color it or use the gradient tool on it. It is only two layer: the background and the vector line drawing. When I bring it into Illustrator I select the gradient tool or the paint tool, but  I keep getting the "not allowed symbol" (circle with the slash through it icon) every time I hover over my illustration. I am more new to Illustrator so maybe there's an easy fix, but I can't find an answer or figure it out.

Maybe you've combined vector and pixel?

No, I made sure they were vector before sending it to Ai and they show up as vector layer there too 😕

Can you show a screenshot of the document open in desktop Illustrator with the layers panel visible (and objects inside layers)?

Here is the fresco document and the document when in illustrator.

The name of the document in Illustrator has a .psd extension, which indicates a Photoshop image.

What is in that top layer? 

Are you sure you sent this to Illustrator via the Fresco function?
