UI11 is rendered when navigating from a catalog item in Service Portal to backend UIIssue Navigating back to the normal UI (home) from a Service Portal catalog item may render UI11.ReleaseAll releasesCauseThis can be caused by the incorrect usage of a system parameter named "sysparm_device." This parameter is used to determine whether to render the mobile UI or normal UI. Typically this is done in a script running against a particular catalog item.ResolutionWe recommend renaming the occurrences of 'sysparm_device' to something else, which will no longer cause the backend UI to change when navigating back to Home.
