You are 99% a genius! Why not
?
Because I have to rebuild dozens of Choice components: it works with the new component (after CSS was implemented), but not on the old ones (before CSS was implemented).
→ No choice made on none component = “Done” inactive:
→ Choice made on the component created before CSS was implemented (without visibility condition for the test even on the components that are actually required) = “Done” active
Many thanks @ThinhDinh
