At the beginning of the season, many radio problems were reported, but they should be fixed now.
You need to test autonomous thoroughly. Refer to this document:

and make yourself a competition dongle. Then, reset the robot and put it in auton. Then turn auton off, reset the robot, and put it in auton again. Wash, rinse, repeat until you are sure it isn't going to do anything. Then blame it on the radio.
And yes, I will try to help, but you need to test it well first.
