GardenArch review for Sitemap NoIndex Pro SEO

This app ruined our website. our SEO was working properly we wanted to exclude some specific pages but we ended from 15K page discovered in our sitemap to 2K, everything collapsed within 24 ours, 4K from indexed pages to Crawled - not indexed. I thought the app would help us improve our website but we're staying awake to resolve the issue (app uninstalled)
