Go 4 App Transmission Frequency

[snowghost]

I'm using a CrystalSky with a Phantom 4 Pro v2, and set the video transmission to 5 GHz. But every time I start a new session the setting is changed back to Dual. Is that supposed to happen? For all the time I've been flying the Phantom 4s, never bothered to override the default before.

Thanks in advance.
