How do I change or delete a First/Last Day photo in a grade album?

From your child’s profile page, tap the icon for the grade you wish to edit. Select the First Day or Last Day button above the photo to display the photo you’d like to change. Tap the three dots [...] in the bottom right of the photo, then select Edit, Share or Delete icon. When you select Edit, you change the photo by tapping Change Photo on the bottom left. Any changes made to the photos within the grade album will automatically update the photo in the First/Last Day Highlight Reel.
