You can trigger the Rewind notification every time you have something to look back on and reflect on from snippets you’ve created in the past.
You can enable this notification to show up once a week or every day that you have a Rewind available to see your throwback content.
How to enable Rewind notification:
Tap on Profile > Tap on Settings > Notifications
Enable "Rewinds and Themes" to turn on the Rewind notification
Tap on "Notification preferences" to customize how often it triggers. Select "Rewind Weekly" to trigger it once a week or "Every day I have a Rewind available!" if you wish to receive a daily notification when content is available.
