Given that’s on config apply, it’s actually probably the use of FusedCANcoder for the steer motors. We fall back to RemoteCANcoder in this instance, so everything will still work, we just also report a UsingProFeatureOnUnlicensedDevice error to alert the user.
If you don’t plan on using Phoenix Pro and want to get rid of the error message, you can change the TunerConstants FeedbackSource to RemoteCANcoder.
