That would mean there can be a lot of various user journeys, much more than you can put together in your funnel report. So, how should you analyze all of them? You can build the only funnel in details (it should be the funnel users go through most) and a few smaller ones. It is a nice option if there are not too many users. If you have quite a few users, build even more, and more, and more… Compare properties, apply segments, and so on… Till someone does it for you. For instance, an algorithm.
AI that revisits all user's steps and events fired, compares event and user properties, calculates statistical significance, identifies user segments and shows the user journeys that convert better or worse.
