CENTURY is now optimised for use on mobile phones.

We still recommend using CENTURY on a tablet or laptop. If this is not possible, please ensure you are using an up-to-date version of Chrome or Safari and you are using your phone in landscape mode. 

It can sometimes help to go into an incognito browser window and close any other tabs you have open.
