My Phantom 2 V+ 3.0 does not show the percent of power of the wifi extender on the app. The icon is lit up, but it doesn't show the percent of power. This is important to me because I try to store it at 50% to keep the battery optimized. Does anyone know what could possibly cause this? Which wire gives it the reading? I haven't found any loose wires as of yet. Not to say that there is not a bad connection some where. Thanks
