Yeah. Should say complimentary session before plugging in.
Then, you should get a message about Welcome, Driver or Welcome, Free along with something like "This session is complimentary, courtesy of Electrify America". It may show a price which you can ignore. When charging, the $ amount will go up but at the end, it'll show some $ value then a discount for that entire amount.
When you see "complimentary session", just plug in. Don't use their app, CC or NFC. Tonight in the Bay Area, I did see complimentary session still showing on stations from a distance. I didn't get out to double check, but it is very distinctive and in a certain part of the UI.
Here are some examples from previous times EA juice was free.
