Hey All -- The last couple of cold starts (more than 24 hours between flights) my battery seems to hit a malfunction.  Gimbal starts making a constant sound and I get an error signal on the Go App.  Starting up following protocal -- battery first, RC next, and last open into camera view on the app.  When I turn the battery off, the power buttom flashes red for about 20 seconds before completely turning off.  I restart the process over, and everything works fine...  I don't want to risk any serious malfunctions if this is the sign of something critical.  Any ideas??  Thanks!

I dont know if it will change your result but you should always turn on the remote before the P3 and turn it off after the P3.

StephLed if I'm reading you right, you are saying you're start up sequence is Batteries,R/C and then app? If so you need to start the R/C, the app next and then the battery (Phantom).

I hope it's that simple of a fix!  Over 75 flights, and this just started recently.  Will give it a try -- thanks!
