Mine still says that, but, I really don’t think it is as it’s not communicating correctly with the car API.
No matter what time I connect it now it starts charging immediately, it still says all your charging will be at the off peak rate. But, the first time it did this (about 8pm when I plugged in) it also said it was going to charge from 0 to 100% with an end time of something like 12:45pm the next day, that would certainly not have been at the off peak rate.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
