Very strange problem.
First - erased and reformatted 128 Gb Blackvue SD card. Then - upgraded to 1.005 firmware release by copying /Blackvue folder (as suggested).
Connected to the unit via Wi-Fi and noticed that only one front and one rear files were available to view.
Attempted to view both files via Blackvue app. Received an error - unable to read.
Decided to format the SD card using in-unit function (by pressing WiFi button).
The problem disappeared.
