In the Survey123 Web Designer, setting the max character count in a multi-line text field does not change the field length if the value is greater than 255; if a user sets the maximum characters to above 255, the limit will still be 255. When pulling the xls form into Survey123 connect, the constraint is set to the max character limit, but the bind::esri:fieldLength value is blank. setting the field length in Connect works as intended. Setting the maximum character limit should also change the field length.
