My adviser for my robotics club bought us VEXnet Competition Switches to help us practice our autonomous program. The switch was brand new and when we attempted to switch from driver disabled to autonomous disabled the switch would still allow us to drive. When we enabled autonomous it would still allow us to drive and the program would not run.
Essentially, the switch is stuck on driver control enabled and wont switch out of it. This is for VEX EDR and im using robotC.
