404 Link Monitor

The reviews for this Shopify App are overwhelmingly negative, with users reporting issues such as the app not opening and the website being inaccessible. Additionally, one user mentioned that the app found 430 error codes on their pages and suggested redirecting live pages, products, and collections, which could be risky for inexperienced merchants. The lack of a feature to view only 404 errors and dismiss strange 430 errors was also a point of dissatisfaction for the users. Overall, the app seems to have significant functionality and reliability issues, leading to disappointment among merchants.
