Honestly, I was a little amazed to see this essential form requirement lacking in such a well-rounded product offering.
I appreciate the multiple-choice options offers a workaround, but it’s just that a workaround. It lacks the binary on/off option of a single field that’s required for so many use cases. Privacy/Terms acceptance being the most obvious.
An issue with the workaround; once a single multiple-choice field is selected, there’s no way to deselect that item. So if chosen in error, the user has to reload the form.
