I go to Missions but it takes me to buy the book. I have 2 emails which I can login with but not getting to missions. What should I do?

This would only happen if you try to login with another email id other than the one you registered with and in which case this becomes a case of conflicting duplicated email ids for your profile on the system. To solve this issue we would need to reset your account by deleting both these ids from the system so you may restart on this. Should you be willing to go ahead with this kindly contact support - the process may take from 6 -14 hours.
