What happened ?

I'm trying to follow the official example (v1, v2 not found) of running two cards. but i can run always just one alone, never together. the second card initialization is always failing, why?

I'm using esp32 DevKitC v4 on PlatformIO with Adafruits SdFat version 2 (version of Greiman not working too with me). Please Help.

How to reproduce ?

I'm using the default SPI pins 18,19,23.
CS for card 1: 5
CS for card 2: 13
