We have an ArcGIS Online web map used in Collector which has stored credentials in a feature layer hosted on ArcGIS Online. The new versions of Collector (18.1.0) does not recognize the store credentials and asks for the credentials for each layer in the Feature Layer when downloading the map for offline use. Is this expected behavior in the new version of Collector or a bug? The "Classic" version of Collector does not do this. It simply downloads each layer without asking for credentials.
