So guys - yesterday at a brand new BTC units at the Anthem Outlets Walmart here in AZ - plugged in super excited to see what speeds etc I may get, and very sadly for the first time, I got that dreaded Authentication Error message 5 times in a row within a few seconds of me plugging the cable into the car. Called EA and they seemed like they'd never heard of the issue (perhaps just this rep specifically). However they tried restarting the unit and taking away the "complimentary session" that showed up on the screen coz of their Thanksgiving goodwill. I kinda remembered reading here that one of the issues maybe with that free session. In any case, they could not get my car to initiate charging and warm transferred the call to a Lucid CC rep! That rep had me try to use the app to initiate charging and that didn't work with the first try. He asked me to move to another spot that had finally opened up (BTC again) and magically - plugged in the cable - started charging. What is the latest on how to overcome this the next time I timidly go there for charging?
