I upgraded to the latest firmware 1.3.0 Build 20221208 rel.45145(4555).  Since upgrading i have been unable to find where the traffic monitor has gone - it used to let you analyse per device what network usage was.  It was under Advanced | System Tools | Traffic Monitor.

Has this feature been removed or has it just moved somewhere cryptic - i've searched everywhere i can think of.

It was a really good feature and included graphs etc - if it has been removed that is disappointing and it should be returned.
