nrf52833 not waking up on custom board

Question

Hi every body, 
 
 My system was able to wake up on gpio on dev kit but after adjusting pin , my custom board is not able to wake up. 
 I'm in debug mode, it was also working fine. 
 My second question is that i don't know why i have to call two times idle_state_handle(); 
 After first call i see the wake up debug pin togle fast . After second call, wake up pin stay high so module is properly in sleep mode. 
 
 case LOW_POWER:

 NRF_LOG_INFO("State Machine : LOW POWER");
 
 
 idle_state_handle();
 idle_state_handle(); //why two times ? but it works...

 //ZZZZZZZZZZ... Program sleep here, willcontinu after this comment on wake up

Here how i set my pin P0_30/ain6 to be able to wake up the system. I checked by reading that the pin is properly soldered and it is the case, that's why i'm thinking to a configuration somewhere to adjust. 
 
 //pin wake up
 nrf_gpio_cfg_sense_input(ACCEL_WKUP_PIN_NUMBER,NRF_GPIO_PIN_NOPULL,NRF_GPIO_PIN_SENSE_HIGH);

Thanks a for your help !

Thanks Jorgen, i found the issue, as dev kit had button management that i removed cause no button on my board, ome gpiote init function was removed, with interrupt management too. i just had thisto solve the issue: 
 
 err_code = nrf_drv_gpiote_init();
 APP_ERROR_CHECK(err_code);

 nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_TOGGLE(true);
 in_config.pull = NRF_GPIO_PIN_NOPULL;

 err_code = nrf_drv_gpiote_in_init(30, &in_config, in_pin_handler);
 APP_ERROR_CHECK(err_code);

 nrf_drv_gpiote_in_event_enable(30, true);
