Hudl 2, Android 5.1?

I have a Hudl 2, I have heard lots of people claiming that they have installed Android 5.1, I contacted support and they said that you have to wait until your device is ready? Which I have no idea what that means. I asked her how to get your device ready, she said you just have to wait..... Is there anyway I can get my device "ready", so I can get the update. I am currently in New Zealand, I have tried updating on a VPN as well, as reseting my device. My Hudl 2 currently has 4.4.2 on it.
