If it's any consolation, the failure to transfer DNG files via wireless is not restricted to DJI; it's the same with other cameras. None of my cameras with WiFi capabilities support WiFi transfer of DNG/RAW files to my mobile devices.
Maybe it's the large size of DNG files which would impact transfer performance, or maybe because there are not that many apps that can display/process DNG/RAW files. You can put RAW files onto an iPad (not wirelessly) for example; but what is displayed in the Photos app is the imbedded JPEG in the RAW file.
Personally, I don't find this to be a problem. If I feel the need, II transfer the JPEG which is taken along with the DNG to my phone and use that for simple editing and on-line sharing; and then stick the DNG files on my computer when I get home for any more serious processing.
