What breaks most often in your redirect or smart-link setup?

We're preparing UrlEdge for launch and would love to learn how teams are handling redirects today.

If you've dealt with domain migrations, smart links, app-store fallbacks, or campaign routing, what tends to break first?

- origin or server config drift

- analytics attribution loss

- device or geo fallbacks

- bulk rule changes and QA

- SEO risk during migrations

We're especially interested in workflows people still piece together with Nginx, DNS, spreadsheets, link shorteners, or custom scripts. Real pain points are more helpful than feature requests right now.
