Weak Signal Phantom 3 Advanced- HELP

[Ged2217]

Hi guys, I have a P3A and Flying today in perfect conditions.. not a cloud in the sky, 17 satellites connected with a altitude of 100m my bird was approx 450-500m away and I get the weak signal warning! This time last year I was able to fly 1-2 miles in the same field without issue. This weak signal problem is happening every time I fly recently.
Does anyone have any suggestions or have DJI changed, reduced the distance limits in the DJI GO app?

Thank you in advance

Have you tried to fly at a different open area? Recalibrate the IMU?
