Hi Megan,
Okay so I set up the Mobile Banking App on my phone.
It's activated and working fine, I can view my accounts etc on my phone.
So I go to the laptop and go to the 365online home page.
I log in to the same old site with no changes?
As in I enter the normal details from before and get presented with the same 365 site I've known for years with no changes either to the authentication process or how the site looks which has the same look and feel.

The guide says "When you log on to 365 online for the first time, you will be asked to set up your “security device”."
I was never asked to set up a security device.
So my phone has zero interaction with my laptop login.
The only conclusion I can come up with is that the new site isn't live yet?
