shouldn't SS be GPIO 5?

The ESP32's "General purpose SPI" can be remap to any GPIO

true, but it will not work just by defining it here ;)

OK I'm merging this now and will make the necessary adjustments to make your SS pin work.
Keep in mind that GPIO2 is a bootstrap pin that is pulled down by default (like GPIO15 on ESP8266) and that does not make it a very good SS pin, because it will have the slave selected on boot.

I agree with you, changed the SS to GPIO5.
Thank you.
