You can change the content clipped to "Today's Cover" at any time by following the steps below.
On the timeline, tap the clip icon of the other content you want to set as the cover.
When the confirmation dialog "Replace the cover?" appears, tap "Replace" to complete the change.
*With the Free Plan, if you unclip a photo from the cover, it will be removed from cloud storage. Please note that if the photo does not exist in your device's photo library, it will no longer appear in the app after being unclipped from the cover.
