I got the SD Card Error message when I took DNG+jpeg photos faster than they were writing to the card. If I waited until the photo count incremented, then no error. Since it was a repeatable bug, I can easily check to see if they fixed it.
The bug is fixed. Now when I take DNG photos faster than they write to the card, the shutter button (on the app) is disabled until the photo count increments. I did not think to test the shutter button on the controller, but will test it next time.
