Hello,
I have yet to get the M-300 to fix , its always yellow and converging, and thus yet to use this feature. Appears to have decent signal....does it need stronger WIFI signal to fix?? At a loss for the state of NC says they have no issues with other drone pilots using the system. Let me know if any of you got it to work.
