Issue Summary

Affected apps:

• Simply Forms

Steps to Reproduce

1. Install the an app that relies on URLs to work (e.g. Simply Forms).
2. Create a form and save the link.
3. Set up a custom domain for your Confluence instance.
4. Try to access the link that uses the old URL.

Expected Results

The link using the old Confluence URL should automatically redirect to the corresponding page on the new custom domain URL.

Actual Results

The link does not redirect, and users are not taken to the correct page on the custom domain.

Workaround

Manually fix the links by changing the old base URL for the new one.
