I've hit an issue now.
When I originally installed the new app it seemed to work fine. I could follow the car charging wherever - on the granny lead, at a DC charger and at a public type 2. But then today, charging at an Instavolt, although the main page correctly showed me the state of charge and the range, tapping on the "battery" tile failed repeatedly. I was never able to see the charging power or the estimated finishing time, although I tried repeatedly to refresh.
Now I'm home and the car is on the granny charger, the same thing. Every time, "The remote control instruction failed, please try again later." It's getting the basic info to the main page, but the "EV Management" page ain't playing.
