Lightroom mobile camera does not save pictures

When I shoot pictures using the ligthroom mobile camera in Auto or Pro modes, the pictures are saved only if JPEG is selected. As soon as I switch to DNG, the pictures are not saved.

The pictures are saved in DNG if shooting in HDR mode though, so not sure what is the issue to save DNG pictures in Auto or Pro modes.

My phone is a Samsung Note20 Ultra, android 13, lightroom mobile app version 9.00

Thanks
