The simplest way to fix broken link previews in Buffer is by editing the post and reentering the URL straight from the address bar of the web page. Here’s a short guide on how to do it:
- Inside Buffer's Publish tab, find the post that contains the broken link preview and then click its 'Edit' button.
- After that, navigate to the link attachment right below the caption and click its 'X' icon to delete the broken link preview.
- Tap the text field, then paste the link anew. Make sure that it is copied directly from the actual address bar of the webpage to keep the preview intact.
- Once done, click 'Save Draft' to apply the changes.
- After completing these steps, the broken link preview in your Buffer post will be fixed instantly.
