We should be more wizard like, and directive on the product scan card when we have neither Nutri-Score nor Eco-Score.
Eg: prevent the user from accessing the product and forcing him/her in the pipeline ?

And the wizard is the final boss, right?

That said, the first thing would be to move all the "please complete" KP action buttons to the top.
Would the KP action buttons be enough, I mean, are there other action buttons that cannot come from KP but that are very important?
An alternate solution would be, as I mentioned earlier, to hack the scores / product completion: the 3 more important data about a product as completed/not completed buttons on top of the product page.
