Hi Jim,
The sharing of surveys on the Collaborate tab is designed to properly configure surveys for a given task; however, it sounds like you might be setting up a situation when you share to other apps that might be causing the issue you are describing. To address issues like spurious data submission, Survey123 has implemented a slightly more complex than normal sharing model that you might not be taking advantage of.
Note that there are 2 sharing options on the Collaborate tab: Submit and Analyze
The Submit option is to share the survey to people collecting the survey results. If a survey is created via the Survey123 website, this will share a Feature Layer View whose settings are restricted to submit data only, noted by being named '[Form Name]_fieldworker. If created via Survey123 Connect, this will share the Feature Layer of the survey; you can restrict access through the Feature Layer Settings.
The Analyze option is to share the survey so that the results can be viewed. This creates a read-only Feature Layer View, names '[Form Name]_stakeholder'. This Feature Layer View is what should be used in other view-only applications like Story Maps.
