Visited on August 31 and did a short charge with eCarUp app.
They pasted the corrected eCarUp QR codes on top of the original eCarUp QR codes. I checked the charger serial number, it's the same as in September last year, so they didn't move the chargers around physically, it must have been a print error.
There's a new tariff sheet in the same style as the old one, but explaining the eCarUp price.
Even though there's a language selector on the screen, every time I returned to the charging screen it was in German.
