Maybe I'm not understanding which ball notes you are trying to read, but:

I think its actually easier to find them on the Surface than it was on the paper charts.

There's two ways to see them.
You just zoom in to the area where you are crossing the FIR boundary and then you can either 1) click on the little notation icon on the lower left of the screen and a list of notes pops up, or 2) touch the little dark blue "i" on the chart. When you touch the i it usually brings up a box that says "Multiple Objects". Select the FIR/UIR you are entering and then touch "Notes".
