I used to do 2 miles with great video. Now after the last two updates, the video cuts out momentarily. This is at just less than a mile. Go app said crappy video signal, most are red, and this is set to auto. Seems to jump around a lot.
Set the transmission rate to minimum and try the distance then.
We had heard that in view of limited range of P4, P3 range will also be limited. Not sure if that's true. So far you are the first to give this message.
