Favorite Team Achievement Guide
When you go to link your ESPN account afterwards you can scroll down to add a favorite team, and a favorite sport. A known bug is it will tell you that this option is unavailable. In that case you go onto the ESPN app on the computer and manually add a team, and a sport. Then go back into the app sign out, and sign back in again, and the options will not be unavailable anymore. You may have to back completely out of the app and quit it and re-open it for it work.
