BSF App answers are not saved to a specific device but to a specific user account.  Answers for a specific account will display on any device after the user signs in.  If a user wants to change the email associated their BSF account, the answers will transfer to the new email automatically if the new email is not already in the BSF database.  However if the new email is already in the BSF data base, the following steps must be taken to transfer answers from one email account to another.  Note:  A user is not required to be registered in a BSF in-person or online group to see and answer BSF lesson questions.
