I've had my Mavic air about a week and I am getting frustrated. I cannot seem to go beyond 300m distance. I have tried both 2.4 and 5.8, to no avail. Regardless of where I take it I begin to lose connection. Weak signal warnings, losing video feed, etc. I'm considering taking it back for Mavic Pro as I know RC is more reliable than wifi. Please help any way you can. Thanks.
