At least v4.1 does not take into account that ESP32 chips can have an usable GPIO20 yet. We'll see if we can add/backport this. For now, you may be able to make this change to make it work: in esp-idf/components/soc/soc/esp32/gpio_periph.c, search for 'IO_MUX_GPIO19_REG' and change the line under it from '0,'to 'IO_MUX_GPIO20_REG,'.
I use IO20 as input an it work well with ESP32-PICO-MINI-02 module.
I don't understand why there is no ANY information in the official documentation; Give it but without telling anything about it. How ridiculous! :!:
