Does Robinson ever have Vision make an appearance? Or does he even touch on that history?

Vision hasn’t made an appearance in Scarlet Witch vol. 2, no. He has been briefly referenced in the last few issues: 

Scarlet Witch v. 2 #8

Scarlet Witch v. 2 #9

What Wanda is referencing in #8 is likely West Coast Avengers v. 2 #45, when Vision loses his emotions. It is ignoring that he regained them, they reconciled, and got back together shortly before Disassembled in Kurt Busiek’s, then Geoff Johns’ run. It does, however, raise the fairly decent point that’s been raised only once before: why did none of the Avengers try to help Vision? We got an explanation from Tony for most of them, but it’s never been addressed with Wanda. This issue posits that Wanda has been too paralyzed by her history to confront it, and thus ignored Vision’s remains and refused to face what she did–kill her husband.

As for #9, this is taken directly from Englehart’s characterization of Pietro as a controlling brother who saw Vision as little more than a toaster. He didn’t feel that way before, and hasn’t felt that way in a long time. But as I said in the previous post, Robinson is making Pietro the villain of Wanda’s past, so it’s not surprising he drew from the era in which they were most at odds.
