Select the Snap you wish to delete by going to your Profile, tapping your Story under 'My Stories,' and then opening it. After choosing "Delete Snap" and confirming, swipe up or hit the trash can icon (or three dots). You have to remove each Snap separately.
To delete a Snap story before 24 hours, open Snapchat, go to your profile, tap on My Story, then press and hold the snap you want to delete. Select Delete Snap, and confirm. It will be removed instantly from your story.
Easily deleting a Snap story is a simple process, all you need to do is go to your profile, select your story, and then either press the three-dot icon and choose "Delete Snap" or swipe up on the Snap you want to delete and hit the bin icon. In the case of multiple Snaps, you can either tap the three dots on the story to delete them one by one or see each one and delete it one at a time.
