I have a problem...
There is a collection of categories in an application.
In the Users collection, there is a category row (List <Doc Reference (categories)>.
The user has to select multiple categories from DropDown.
The “Next” button should save the selected categories to the current user's data.
Everything seems to be set up as described in the documentation, but when composing an action, I can't set the required property when adding selected categories from DropDown.
Please help me to understand what I did wrong....
