Slight topic derail - apologies.
I'm newly joined to Southern Cross (Health Insurance) - why would I want their app on my phone?

You need to be exactly perfect with your details - it wouldn't email me a code when I put "Tim" in as my name, it wanted my exact name as recorded which is of course Jimothy.
