A user receives an "Access is denied" error when trying to open an app in a secured stream. What might be the reason?

The most likely reason for a user receiving an "Access is denied" error when attempting to open an app in a secured stream is related to section access excluding the user from seeing the app. Section access is a security feature in Qlik that allows administrators to restrict access to data at a granular level. If the app has section access set up that specifically excludes the user, they will not be able to view the app, leading to the access denial message.

This scenario emphasizes the importance of configuring section access correctly to ensure that users have the appropriate permissions to access the data they need without exposing sensitive information to unauthorized users. Proper management of section access is crucial in maintaining data security and integrity within applications.

The other reasons given do not directly lead to an "Access is denied" message related to app access. Being set to a delivery group, not being logged into the system, or being incorrectly configured in the QMC may contribute to access issues but are not specific causes for the denial associated with section access configurations preventing visibility into secured content.
