Has anyone else had problems with the Chargepro network that appears to be ubiquitous at Walgreens? I don't have a Chargepro card but the instructions displayed by the unit state that you can use your card OR just start charging, presumably because they're not charging for, er, charging. Seems simple enough. Once plugged in the station claims it has started and then stops shortly thereafter, and shows that charging is "complete." I have used my J1772 adapter with ChargePoint stations successfully. Any insights? Problems or successes?
