Deco system set in Access Point mode.

Open the mobile app, see the "OVERVIEW" page.

All the connected clients are listed in the Device List.

The upload / dowload indicators, in Kbps, do not show any real traffic data, they display zero.

The same if I go the single access point page, where the two big Download / Upload indicators stay on zero, and cannot display the current device throughput 

If deco system is in Router mode, the indicators are working.
