We’ve fixed issues with the Choice field and conditional logic in our Forms 
.
Previously, in the Multistep form, the Choice field wouldn’t save the selected value, and the conditional logic didn’t consider the dependencies of child fields. This meant that when you hid the initial fields in a chain, the following fields would still be visible.
Now, when you change the visibility of the initial fields, the subsequent fields will also be hidden, ensuring that the form works properly.
