Do you use Machine_USB_V5.ino ?
You should post screenshots (AGIO, GPS related, (touch speed signal in aog main screen and you get Hz )… ) and pictures of hardware nano /relayboard, which pins you are using?
If you driving the tractor, and you are simulation mode, do you have the same fault?
There is another section software, look at:
Section control by Switch - Hardware / Section Control - AgOpenGPS
