You can select which queues are visible by clicking the Settings button in the Sidebar and clicking Queue Selection. You are still offered interactions for the queues to which you are assigned, even though they may not be visible.
Ignite can display a maximum of 64 queues. If your profile is new, from an upgrade, or has been restored from a reset, Ignite automatically loads the maximum number of queues, starting with Unified Queues and then Individual Queues. Queues under Reporting Queues are never loaded by default.
