Im not sure about this one, sometimes we want both a back button and a close button, for modally presented flows. Have you verified that those still work, i.e. that you can both go back and close?

[matiasbzurovski]

I haven't seen any flow like that (back button on leading, close button on trailing). In fact, I would even say that it isn't a desired UX to have.
Do you have any example I can check @CyonAlexRDX ?

@matiasbzurovski i can't find it either now - so maybe we have long since removed that. But worth raising with Matt! Eg create persona flow - it is a modally presented flow, after first "intro screen" in the flow we push "name persona screen", from which we can (have in the past?) have a back button on left in nav bar and a close button on the right.
