Sirius XM app shutting down when using Favorites tab

iOS and iPadOS
When using the latest Sirius XM app 2.20 with IOS 6 both on a 4S and 5, the app automatically shuts down when using the favorites tab in exactly five minutes. This has been reported to Sirius XM twice with no response. Has anyone experienced this, and if so, is there a work around? Note that the app stays open when using any other tab except the Favorites tab.
