How do I delete a message in my history?

Only the board "owner" can delete any previously sent messages from the Vestaboard's history. 

Within the mobile app:

1. Tap Messages icon (located to the left of the Home icon, at the bottom of your screen) to open your History. 
2. Select the message you'd like to permanently hide and hit the Trash icon in the upper right corner of the message card. 
3. You will then be asked to confirm the deletion of the message. Once confirmed, the message will be permanently removed from the Vestaboard history for every user managing the Vestaboard.
