Anyone else downloaded the most recent Onstar Remote Link app for iOS (Apple) devices? I keep getting: Unable to authenticate. (403_999) error. [Retry] [Try Later] This app was flaky at best, but now it seems to be completely broken. I uninstalled and reinstalled it last night, but that didn't help. So far my trial of the Onstar service has been mediocre. I was really interested in the remote app since it allowed starting of the vehicle when not in range of the remote... too bad that it's getting cold here in Canada now and I couldn't use it last night when I actually wanted to.:grrrrrr: They've now removed the app from the app store.
