This one is a bit odd. I have a MP2z and it takes 15 seconds after the record button is pressed to start recording and about the same delay to stop. This is very annoying as if the record is not properly stopped and I shut down the drone the recording is damaged. So I have to wait and wait and once the recording stops I can safely shut down. I normally use litchi but this also happens with the go app. All firmware is current and I just updated in hopes the new release would fix this glitch.
