Frustratingly, the app has never worked for me. And the credit card readers have been trash as well. The only two times I've been successful in charging at an EA station have been where I've called-in and they've re-started, then remote-started the machine. Oftentimes it's after the machine was stuck initializing for minutes before failing after trying to use the app.EA is wonderful, I have never had a charging site failure since the advent of the EA app. I never have to call tech support now. I have been relegated to a 3 hour L2 charge by a chargepoint failure, and almost got stranded by EVgo.
PS: I am sure that you have seen people on several occasions say that getting the app solves the payment problem... if you chose not to do so that is not a failure on EA's part.
