When the last iOS app was released it introduced a bug where people with special characters in their passwords could no longer sign in. The workaround was to change your password to remove the special characters (sigh). I tested the app just now and it appears the bug still exists? Can anyone confirm what I'm seeing? I guess I'll go change my password...
Wasn't it the most recent app update that introduced this? In which case it would certainly still exist.
I had no access via IOS app for 4 days and went through all of the troubleshooting and finally removed the "!" In my password and it is working. Strange that I had access ever since the app came out and it stopped allowing me with that password just over the weekend.
I confirmed with Ownership that this is, in fact, a bug introduced in the 1.1 version. Very frustrating, and certainly a head scratcher that such a fundamental flaw would be released to production. I had resigned to not use the app until it was fixed because I have a sufficiently strong password and do not want to change it now. But, as inconsequential as it may seem, having the app is really addictive and it's a great showcase for the car's tech when you're talking with people about the Model S. So, I'm back to using the 1.0 version. Google "iTunes revert to previous app version" and follow recommendations for your particular OS.
