How many times can I use the same activation code?
The activation code is one-time use only and can only be unlocked by one account.If you would like to share your unlocked stories with other users, you also have the option to share your stories. In the main menu, click the Settings icon on the bottom right of the screen and tap “Share My Stories.” You can share stories with up to 3 other users by entering their emails in the field provided.
After you have successfully shared stories with another user, he or she should receive a confirmation email. These stories should now appear in the user's collection ready to download the next time they sign into their account.
