Users don’t flow in ONE WAY ↔️

My Problems with Funnel

1. it assumes users flow in ONE WAY

which in most cases, it's not, you don't control how users interacting between funnel steps, UNLESS there is NO 🔙 options for users

1. it doesn't show the opportunities for improvement

the opportunities sit where the users/traffic don't go into next step

opportunity: how many users back to `payment_sdk_view`~fromStep from `has_intent`~toStep then drop off? what improvements we can do on tickets checkout page to drive them back to checkout process or interview them why you get back to previous page end up NOT buying tickets
