Please follow these steps to troubleshoot it:

1 - Verify if your Checklist is active and if its Page Targeting rules are valid for the current URL you're visiting.

2 - Confirm if you have selected the right Segmentation and Container.

3 - Ensure there aren't two or more Checklists targeted to the same URL.

4 - Make sure that you have published changes from your Panel and that your MAU quota has not been exceeded.

5 - Try running the Troubleshooter on the URL where it should be visible. If the Troubleshooter does not run, check your UserGuiding installation.

6 - Finally, if none work, try clearing your browser cache and flushing your DNS.
