[2019] iOS 13 controller L3/R3 support

I was able to download iOS 13 public beta on my iPad Pro. Easily paired my Xbox controller to my iPad. Then I enabled builder pro in my settings.

But I’m unable to use r3 to crouch, they simply don’t respond. I know the software is in beta. I was just wanted to put it out therein case epic sees this post.

Any input is appreciated.
