With the collection of a point, I want to display a unique ID on the attribute form. Simple, just display (read only) the OBJECTID or GlobalID field on the popup config in AGOL; this works great in AGOL. Problem is Collector does not display these fields in the attribute form, regardless of AGOL popup settings.
I can see why: the OBJECTID and GlobalID values will likely change pending a sync with the master db in offline mode.
Any other workarounds to generating a unique ID with every point collection?
