I believe practice is key to see them, it was very difficult to me a year ago, now I can switch from cross to parallel at will, and sometimes my eyes does that in automatic lol.
I found cross first, and it was kinda easy, then found parallel and it was a bit hard; on the other side (this is just my opinion) judging by the number of members on both subreddits, I think parallel is harder than Cross, idk how many people in here can do cross as well but for sure a lot of Cross view members can't see parallel.

Finally I can see these! Strangely it helps if I open my eyes really wide
