ESP32 has 18 ADC input channels. But if you are using Wifi, you can only use 8 of the 18 for ADC conversion: GPIO pins 32-39.

Other 10 pins, on which ADC2 channels are possible, can only accept pulse data if you are using Wifi.

This is probably due to firmware limitations.

Espressif implies that the WiFi hardware uses ADC2 for something. It sounds like a hardware limitation, a firmware issue would have been patched a long time ago.
