Starting this week, we are getting an "Unable to Submit. Service does not support applyEdits with GlobalIDs" error message when trying to submit a record on a related table, using the latest version of Fields Maps (iOS v.23.2.3 Build 1019). To my knowledge nothing has changed with the data or web map in Enterprise from our end (since early June), and the submissions were working at least up to July 31, 2023.
