Review CSV imports before they make changes

Bulk importing redirects should be predictable—whether you’re updating a handful of URLs or a much larger CSV.

With this update, every CSV import now follows the same review-first flow:

Validate before importing — We check your CSV before any redirect is changed. If there’s a problem, you’ll see the affected rows and what needs fixing. 
Preview before committing — Review your import before applying it to your workspace. 
One consistent workflow — Small and large CSV files now use the same import experience. 
Prevent duplicate imports — Once an import has started, it can’t be accidentally submitted again. 
Clear completion status — Follow the import status in the dashboard and receive a confirmation when it finishes.

This update also applies the same review-before-change approach to CSV-based redirect deletions.
