I have update 70mai pro on Sunday (to 1.06na) and I have found option to change recording duration. Now I can choose 1, 2 or 3 minutes. I have checked ADAS (working OK), voice commands (working OK), GPS speed and coordinates (working OK).
I can't remember that I saw option to change/disable watermark.
Apparently, option to change/replace logo is in updated app. There were no update for Android app on Sunday (when I have updated my camera). Now I have found update for app, but I'm not near the camera right now. I will test it later.
