MD_MAX72xx library on teensy 4.0

[JanezO]

Hello,
I'm new to teensy and when I tried to use a program that uses the MD_MAX72XX library, it gives me this warning:
#warning "INFO: ARDUINO SPI interface selected." It doesn't work properly. Does anyone have any idea what's going on and how to fix this?
