Capture Shapes not working in Illustrator on iPad

I can place an Adobe Capture shape in Illustrator on the desktop, and it behaves as expected: one fill color that can be changed, no clipping masks or difficulty selecting.

However, on the iPad, the same Capture shape is placed either as an image, or sometimes as paths that are grouped and inside clipping masks. When you try to select and change the fill color, it's not possible because of excess clipping masks.

The only workaround is to place the shape in a desktop cloud document and open on the iPad, but shapes created in Adobe Capture should work everywhere - and they used to work on the iPad.
