During this time you might see some errors on the front end e.g. code in use & performance issues (load times).If you are having problems redeeming your code you could try the following steps;1) Log out of the beta site if logged in2) Clear internet cache 3) Log back into the site and try again4) ... and again I'll be back again in the morning from 9 AM GMT with more updates.Thanks for your patience,
