BUG-000163129: ArcGIS Instant Apps intermittent issue: The template example application is displayed after creating an instant app from a web map's Details page.
- The workaround for this issue is to gather the appid for your Instant App. This can be located at the end of the URL when configuring the app, or from the settings page.
- Once the appid has been obtained, you can go to the Instant Apps' item details page, and under settings, add the parameter "?appid=<YOUR APPS ITEM ID>".
