Please, allow Survey123 to work with related fields other than GUID.
Right now, the documentation says "Survey123 only supports one-to-many GUID relationships when working with existing feature layers and related tables". This is a deal breaker for my project, let me explain why:
I have a tree database that dates back to 1990. This database has two tables (trees and stems), linked by TREETAG, in a 1:M relationship. This treetag field is a string used on the table and printed on aluminum tags attached to the trees.
Field Maps works perfectly with the tables related by treetag but I would like to use Survey123 to update data on the field. Problem is, Survey123 doesn't support relates not based on GUID. But why? AGOL and Field Maps supports it.
Thanks for considering.
