Harry's Camper

I was excited about this app but can’t even get through the set up without it crashing. How do I get a refund?

I purchased this in the bundle with the lap timer since I’ll be using the apps in order to tow my vehicle to the race track with my suv, and use the lap timer on track. I’ve used the lap time on someone else’s phone and it worked very well. However, I can’t even get past the setup screen on the camper app to define my vehicles. Every single time I do so, the app crashes. In the same spot EVERY SINGLE TIME. I’m highly disappointed I wasn’t edit money on an unusable app. Really hoping this can either be fixed so I can simple USE the app period. If not I’ll be appealing for a refund or something.
