      When SMCP mode is clusterwide, the Kiali doesn't show inbound traffic for mesh application, only for for istio namespace.
      (bookinfo has traffic generator and the responses are 200 via istio gateway, so the bookinfo application works and it was set correctly).

      This is because the `istio_requests_total{}` in the prometheus don't contains data for bookinfo applications, only Gateway->productPage (see thread also here: https://redhat-internal.slack.com/archives/CHR7P722J/p1727445666103409 )

      With SMCP mode MultiTenant, it works correctly. (you can try the same reproducer as above, only change mode from ClusterWide to MultiTenant )

      It happens for all SMCP versions (2.6 , 2.5 , 2.4)

      It works correctly with both modes (ClusterWide or MultiTenant) in the OSSM 2.6.1
