Updated the P3A today before a flight and noticed my Anti Flicker is now set to 50 Hz. No big deal right? Wrong. It doesn't want to let me change it. If I choose "auto" or "60" it simply reverts back to 50 hz immediately. My band aid fix today was to record at 24 fps with 1/50 shutter to avoid any potential complications. Anyone else run into this? Did a google search and only found 1 thread on this but no definitive remedy.
