Policy container option missing?

Hi All,

I have no experience with Sophos but been tasked with setting up MDM. 

I have Android enterprise setup but now want to create a policy but use a container, I watched one of the Sophos help videos and it showed on the Device restrictions tab there is an option to seperate device and sophos data, i assume thats the container. 

Although when i go through that policy wizard on my sophos login, i simply dont have that option. 

Any ideas?   Is the container option an additional license or something to be purchased maybe?
