The error I get is to call Lucid to link your car..
No Vehicle Linked
To use remote features, your Lucid mobile
app must be linked to a registered vehicle.
If you are a new Lucid owner, call Lucid
Customer Care to link your Lucid Account
with your new vehicle.
It is there in the App Store, but obviously without a car to link you can't utilize the app. This behavior is no different than the apps that I use for our current or prior cars. I downloaded the app prior to purchase and until I had the car to link up, the app wasn't functional.
