TUNERSYS review for 404/301 SC Easy URL Redirects

This app is fundamentally incompatible with Shopify's native multilingual URL structure. It incorrectly flags standard Shopify language routes (e.g., /zh/, /ja-lv/, /es-ca/) as 404 errors and automatically generates thousands of junk redirects, which has severely corrupted my site's URL structure and SEO performance. I do not recommend this to any store owner who values their SEO health, as it creates more problems than it solves and lacks a reliable bulk-management tool to fix the mess it created itself.
