I keep getting this annoying warning when flying my P3S. I never experience any issues flying the drone when this is displayed. This never came up before the firmware update. I've re-linked my RC, and calibrated the IMU to no luck. Anyone else having this issue? I'm also running the 3.1.2 IOS app.

Have you tired turning on airplane mode - this will switch off WiFi but you can just switch it back on and keep airplane mode active?
