Out in the west Texas Davis Mountains and flying in the canyons, when I banked back to the west and directly into the very bright, late afternoon sun, as soon as my P4 faced the bright sun obstacle avoidance warnings went off on my controller and the aircraft momentarily stopped in its flight, then continued on, does bright sunlight affect / confuse obstacle avoidance - or am I confused (pls don't explain how to turn off obstacle avoidance, I know how to do that, but when your showing your 12 year old grandson how to fly a drone, all safety protocols are operational)
