If you have aCambridge Elevate or Cambridge Learn account and have a new book code, you can add that code either directly to the mobile app by going to the Menu > My Books > + Add a book, or through the web using the ‘Add Books’ option.
If you have a new access code for your Cambridge GO account, you must use the web version and select ‘Add new resources’. For this, please consult: How to activate resources using a code from a book or a card
Cambridge Reader is only an ereader app. If you have a GO account which contains other types of resources (such as Cambridge Online Mathematics, Digital Study Guides or additional downloadable Teacher Resources), these will not be available on the app. Please login via the web to access other kinds of GO resources. I’m unable to see my digital material on the Cambridge Reader app
