Using Adafruit Feather M0 with RFM95 LoRa Radio #6

I am totally stumped as to why I'm unable to get this module to work with a M0. I can take the same module move it back to Arduino Uno and it works fine. I'm using the standard example and changing Adafruit_MAX31865 max = Adafruit_MAX31865(10, 11, 12, 13); to Adafruit_MAX31865 max = Adafruit_MAX31865(12,23,22,24);

Unfortunately, I get this:

RTD value: 0 Ratio = 0.00000000 Resistance = 0.00000000 Temperature = -242.02

I also tried swapping pin 23 & 22 incase I misunderstood the MOSI MISO stuff.
