Problems with Volvo On Call MY2012

Hello, with my 4 weeks young XC60 MY2012 (km: 1200) it is no longer possible for me to check the vehicle status via iPhone app and – what is actually the worst – to program the heater. I have already used the functionality at least 10x successfully. Without problems. At the moment, with Volvo On Call none of the comfort functions goes. What is the registration at the APP and the on-call function out of the car. However, the friendly Volvo Supporter cannot help me any more. Does anyone have the same problems here at the moment? I hope it’s due to the Volvo On Call Services and not to my vehicle. With 2 different iPhones (3Gs + 4S) it doesn’t work any more. I have the Volvo App available in 2 different versions. Both fail. With a 4 weeks young new car this now dampens the still existing optimism and belief in the increased quality of Volvo products since 2004.
