External SPI bus freezes when LoRa is enabled MKRWAN 1310 - NOT same issue as Flash contention #101

I have an SPI device connected to the header pins MISO, MOSI and SCK with CS using pin A5. This works fine until I enable the LoRa interface.

So when I transmit data via LoRa and come back to read my SPI device it fails. The LoRa interface also fails. I can run only one or the other, but not exchange between the 2. I do not understand this as these are completely different sets of pins being used on the SAMD.

I had to move my SPI device to alternate pins and use software SPI in order to get this to work. I now need to add an SD card and having issues with software SPI on that....
