Knowledge Center appears in Unified Navigation even when sn_km_center.glide.knowman.enable is disabledDescriptionThe Knowledge Center module is visible in Unified Navigation menus (Workspaces and All menu) even when the `sn_km_center.glide.knowman.enable` system property is set to false. This means users observe the Knowledge Center listed in the Workspaces menu and under the Knowledge application group in the All menu, despite the system property indicating it should be hidden. This occurs after upgrading to versions Yokohama Patch 11, Zurich Patch 4, and Australia from a previous version, also when the system property is turned off on an OOB Version.Steps to Reproduce 1. Upgrade to version Yokohama Patch 11, Zurich Patch 4, and Australia from a previous version. (If non-upgrade scenario, go to step #2)2. Verify that the `sn_km_center.glide.knowman.enable` system property is set to false. 3. Open the Workspaces menu and observe that the Knowledge Center is listed. 4. Navigate to the All menu, search for "Knowledge," and confirm the Knowledge Center appears as a module under the Knowledge application group. WorkaroundNOTE: A fix is in place in Yokohama Patch 13, Zurich Patch 7, or Australia Patch 1. This means when upgrading to these versions the system property is correctly respected, and Knowledge Center will seem to disappear from the menus. This is expected behavior. To continue using Knowledge Center set the `sn_km_center.glide.knowman.enable` system property to true. For your instance to respect the system property correctly without upgrading versions: Disable Knowledge Center Experience: Go to https://<instance name>.service-now.com/sys_ux_page_registry.do?sys_id=8317ecbf9f6b5210ecf142a4ba0a1c72 Uncheck Active and Save. Make all the below sys_properties to false sn_km_center.glide.knowman.ece.enablesn_km_center.glide.knowman.enablesn_km_center.glide.knowman.redirect.enable Clear cache: Go to https://<instance name>.service-now.com/cache.do. Re-login: Log out and back in. From All Menu type in "Knowledge Center" if there is one showing up, click on the edit icon next to it: Uncheck Active and Save. Clear cache. Log out and back in.
