I had a problem with it a couple of weeks ago. I think it was about the time they said that the old Eco App would no longer work. When I couldn't get in with the new app, I tried the old one and was able to get in on that occasion.
I tried the new "Access" app just now and it worked.
I few minutes ago I tried logging in to owners.kia.com and couldn't get in. My browser had cached my password for that site but after the third attempt failed, I retyped my password and was able to get in.
