[FTC]: Help? Driver phone will not detect new Op Mode

[KinaK]

We are a brand new FTC team. We have created a simple original op mode in MIT APP, installed it on the Robot Controller, scanned, named all components as they are in program, then paired the driver phone with the robot controller phone. The Driver phone will not detect the new op mode. It has, twice, but then it defaults back to the pre-programmed op modes. I updated phones, and updated apps. That shortened the list of pre-installed pop modes, but ours still does show up as an option.

I restart phones, I restart robot, I re-pair the phones. What else can I try?

The kids really want to run more than two motors, they want to write their pop mode.

Help?
