Yeah. We grown being trained to solve those small puzzles that are websites and apps, so we learned _how they are projected_, not how they work.

I mean, we learn that a enroll is normally a flow. Flows have steps. So if you came to the end of the flow and the finish button is gray, you think.

Hum… I'm used to flows. This is a multistep flow. Flows normally need me to fulfill some small checks and won't let me proceed between steps if something is missing. But some won't. Maybe this is one of those? Some flows have warnings in the end, some have next to the thing missing. I don't see any warn in the last screen, so I'll go back every step and check field by field for errors. That'll probably do.

This is the model you have in your mind, of how a website or an app works.

People that came to computers, apps and websites later in life didn't learned the puzzles.
