Well they updated the IOS app yesterday. You have to sign back in, which means write down your account number before installing the update. (they also do two factor authorization, you give acct and PIN, they then text you the authorization code so make sure the "official" phone for the account is handy).
Not much UI difference. Some status updates seem faster (charge status), others are the old send the request sea mail, get the traditional return to sender notice (the "operation declined" message) sometime in the next ice age.
I don't use delayed charge, we don't have time-of-day rates here, so I have no idea if they fixed it. I haven't tried to start the climate control, either by departure timer, or just a remote start.
In terms of feature changes, they didn't do the ones I wished for, in particular, lock doors over the phone, and unlock charger plug via phone.
The consumption displays only give you Miles/kwh, and you get a per "trip" or "extended time" only. What I would like to see is how many kwh (total) did I use on a given trip, and especially per charge. (and while wanting ponies, how about comparable stats on charging - charge rate, total kwh used, and what percentage of full charge that represented.) Of course some of that info should be available under the "car" button on the display, I shouldn't have to use a phone...
