Get Input Mouse Delta with Touch Input?

I seem to have painted myself into a corner. I am moving a pawn with a hit result and rotating it in the direction of movement with the Get Input Mouse Delta node. Everything works great in the mobile preview. When I launch on iPad, the rotation doesn’t work. I’m at a loss. I’ve poured over documentation and tutorials and am coming up empty. I don’t know where to start. I even downloaded the Epic Zen Garden which has functionality very similar to what I’m trying to achieve. When I tried to dissect the blueprints I realized that I was in over my head.

If anyone can at least point me in the right direction as to how to get this working with touch input I’d really appreciate it.

Here’s what it looks like when it’s working:

Here are my blueprints:
