In some instances, when a user shares a single app using the Share > Invite or Share > Manage Access option, the entire space is shared as well.
Resolution
There are two possible root causes. Both are triggered by the user not having the correct permissions to share an app, but having permissions to share the space. In this instance, the system defaults to sharing the whole space.
Qlik is working on an improvement to clarify what you are sharing, meaning you will be alerted you are sharing the space in the future.
The two scenarios:
Sharing applications via fine-grained access control is disabled in the User default or for the user.
This affects all spaces.
To resolve this, either enable it globally or create a custom role that allows the use of fine-grained access control. See Managing custom roles.
The user is a tenant admin, allowing them to share spaces, but is not the owner of the space and does not have Can Manage permissions.
This affects specific spaces.
To resolve this, grant the user Can Manage permissions on the space or make them the owner.
While this is currently by design, Qlik plans to change this behaviour in the upcoming feature to make this action unnecessary.
