In that case..
Sorry. But yeah – it’s not an issue with PHEV or the app directly, it’s the interaction with ccNC and the app, just gotta hope for an update.
One last thing you in particular could try is to set the charging schedule inside the cars infotainment (i don’t have ccNC, but i can’t imagine it being vastly different), and leave the app in power saving mode for a week or two. If the schedule changes, it’s a ccNC only issue (the app just showing you what the car changed).
Not that it changes much, other than the kind of update you’re waiting for (app update vs OTA OS update).
That isn’t going to fix the km/mi issue, of course. Out of curiosity, the car itself shows the correct units at all times, yeah?
