You can't add a story to Instagram after you've already posted it. Once you've shared a story, it's live and can only be edited or deleted.
However, you can add to your existing story by posting additional content. Here's how:
- Open Instagram: Launch the Instagram app on your mobile device.
- Go to your Story: Tap on your profile picture in the top left corner to access your story.
- Add new content: Tap the "+" button to add new photos, videos, or other content.
- Edit and share: You can edit your new content with filters, text, stickers, and other tools before sharing it to your story.
Remember: You can only add new content to your existing story within the 24-hour window. After that, your story will expire and you'll need to create a new one.
