P: Export/Extract DNGs shot in Lightroom Mobile App to Camera Roll or Computer

If you don't use Lightroom CC on your desktop, you can export to your photo roll on your device. You do this by tapping the share button and selecting "export original". If you are on iOS, you can then select whether to save to the camera roll or to Files. In the first case, the image will show up on Photos on a mac. In the second case, you can save the dng to iCloud, Dropbox, etc. and it will sync up to a desktop that way. But all that said, the very simplest way is to just run Lightroom Classic or CC on your desktop.

Georg, let them sync up to the cloud, then they can download to Lightroom CC or Lightroom Classic on your desktop. 

still not finding how to do it

Where are you checking this? When I export original I definitely get a dng file in the photos. Note that the photos app on iOS cannot deal with raw files and simply shows you the embedded jpeg, but they will sync to your desktop through iCloud photo library just fine as seen in the screenshot below. Those files will import and work great in Lightroom. I have never transferred images using a USB cable from my iPhone so no clue whether that works but my guess would be yes.

Another way to do it is to buy an I-Flash Device. A usb with a Lightning connector on one side and an ordinary usb connector on the other side. If you export original from Lightroom to the photo stream you can import it to the usb as a dng file. And then just plug it in to the computer.

Hi, I tried to do that but it was exported as a jpg file

Go into the image. Tap the share icon (the square with an arrow out of it). Hit 'export original'. This should give you a dng file on your photo stream if your file was shot in dng mode.

How?

Yes you can now export original (I.e. Dng if you shot that) to the camera roll

5 months already. Fixed?
