We had similar issue and after 3 hours of trying to fix it, we figured someone forgot to power the Digital Sidecar.

Before powering it, it could only handle 2 CIM motors, anything more would just make everything not work. And even Relay caused it to jerk and become unresponsive. (Same issue as you are having.)

After powering it, all the lights turned on, including the team light, and everything worked fine.

I would double check the wiring for powering the Digital Sidecar to 20 amps breaker. And also see if your team light is working.

Hope that helps.
