FYI- I was using real dash successfully until I got a new device with USB-C I tried a few usb-usb C adapters that claimed to have OTG compatibility with no success.
I did some more research and found this 3 pack for $7 USD https://www.amazon.com/Weduda-Adapter-Charging-Converter-Samsung/dp/B075QH2YB7 So now, using my usb-micro usb OTG cable from before, and this micro to USB C, everything works again. Thought I would throw that out there in case anyone else was having USB C issues.
