Testers didn't understand purpose of stop button

Do users understand what the Stop button is for (and that they are not going to receive any messages in their Mailbox when it is stopped?)

Most participants were confused by this question. They were trying to guess but they weren’t sure if their answers were right. Some guessed that they would receive the messages and they would be saved in the mailbox, they would be able to get them after they run the Mailbox app again. Some assumed that they would lose all messages when they stop it. Others assumed that they would be able to get their messages if they stop but they wouldn’t be able to get them if they Unlink the device, as in that case the Mailbox itself would be deleted.
