KICKR BIKE with Zwift how to guide

Anyone using a KICKR bike with ZWIFT? I just set one up and I am looking for something to tell me what buttons work with what. Still can’t figure out how to select a different path when the “go left or right” options come up on a ride. Steering is straight forward, I have fugured out the u-turn button but beyond that - a pain.

Anyone have a KICKR bike guide? BTW, it works amazing with Zwift. Love the setup, the auto elevates, great gearing, etc.

For selecting paths, I use the companion app on my phone.
What are you using for Zwift: pc, iPad, etc?
