MG2 on iPad pro with usb c adapter?

I’m using the usb c to 3.5mm jack dongle to connect my Tonewood Amp to the ipad and MG2 doesn’t see it as input (only sees ipad micro).
Any help?

Tonewood amp uses the headphone plug for input, it might very well be not compatible with non-headphone plug ios devices. Please contact Tonewood with the issue.
