Hello and good day Robster52. I am sorry to know that you are having these issues with your DJI Mavic Pro. Have you tried to fly your drone to a different location to see if the issue will still persist? Have you tried adjusting the antennas when the warning appears? Make sure your antenna should be on the correct position. And make sure you are away to any possible interference. You may check this video about it. Please keep us posted for us to help you further. Thank you.
