Volvo on call with a new replacement

Hi,
I have successfully been using the HA Volvo on call integration with my wifes company Volvo. Since yesterday, she has exchanged the old car with a brand new one and connected that vehicle in her Volvo on call app. The login credentials are the same as before. However, after a few restarts, HA continues to try to connect to the old car and not the new one. What to do? How can I see it in HA? Is she required to delete the old car from the VOC app for HA to look for another one?
