Non-administrator roles assigned with any administrator-level privileges are unable to configure apps from ArcGIS Instant Apps shared with them in a shared update group.

Workaround

• Use another app builder platform which does not exhibit this issue, such as ArcGIS Web AppBuilder.
• Change the ownership of the Instant App to the specific user. This enables the user to configure the app.
• Change the user role to one which does not exhibit this issue, such as the default Administrator (If administrator privileges are required), Publisher, or a custom role without any administrator privileges (If administrator privileges are not required).
• Change the custom role privilege settings to remove any administrator-level privileges.
