What is the likely cause if a user cannot consistently see the 'Create new app' button while logging into the hub?

The situation where a user cannot consistently see the 'Create new app' button in the hub can likely be attributed to the configuration of the rim node's purpose being set to Production. In Qlik Sense, the rim node setup is essential for defining how services operate, and if the node is set to Production, it typically means that it is focused on delivering specific services and capabilities to users in a live environment.

When the rim node's purpose is set correctly, it ensures that all necessary functionalities, including the ability to create new applications, are appropriately available to users under normal conditions. If there are misconfigurations or an inconsistency in the node's function, it can lead to limitations in user interactions, such as the inability to see the 'Create new app' button.

Other factors, such as user licenses or security measurements like firewalls, may lead to restrictions but do not directly correlate with the consistent visibility of the button itself. Similarly, concerns about cookies might affect user experience but are not related to the rim node's function and configuration. Thus, the setting of the rim node's purpose plays a critical role in user capabilities within the hub, explaining why it would be the likely cause of this issue.
