Based on this document about integrating Survey123 with other apps, there is currently a bug in Survey123 where the labels and name fields of choices in choice lists need to be identical in order to pass filled values into another app, such as Collector e.g. arcgis-survey123://?itemID=36ff9e8c13e042a58cfce4ad87f55d19&field:surname={name}.
Therefore, I tried to design a form where the name and label are identical with spaces between words for readability and a user-friendly experience for end users. However, I received a warning where the form is converted with warning that choice names should not contain spaces. Since this is a "should not" warning and not a "must not" error. I would like to know will there be performance issues if I publish a Survey123 form whose choices have spaces?
Alternatively, I could make the choices and labels both do not have spaces e.g TypeA-18 as opposed to Type A-18 to avoid this warning. However, it is not very user friendly to do so, especially in cases when there will be lots of choices to choose from.
