When changing the device, I understand we need to remove the old device from my account. Otherwise, the error occurs when installing Mobile zone app to new device. But I cannot remove the old device from my account as causing unexpected error.
Hi Masa, Family Zone Support is contactable on 1300 398 326 or email@example.com between Monday - Friday 9am - 4:30pm AWST.
You can alternatively schedule a call back at a time that you have the device available here.
To remove a device, in the web portal, go to settings, devices and select the device you want to remove. Then click remove from my zone.
