In blog post and here CE is on D9 and CS on D10 and it is written that the official documentation is wrong.
I checked with a multimeter my rfnano and D10 is connected to CE (pin 1 on NRF24L01 chip) and D9 to CS (pin 2) as written in the documentation and in the schematic.
so
#define PIN_RF_CE 9 // D9 = Chip Enable (CE) for nRF24L01+ #define PIN_RF_CS 10 // D10 = Chip Select (CS) for nRF24L01+
should be
#define PIN_RF_CE 10 // D10 = Chip Enable (CE) for nRF24L01+ #define PIN_RF_CS 9 // D9 = Chip Select (CS) for nRF24L01+
