Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureShared links often show a random photo or none. Build one template per page type (shop, products, collections, pages, blogs, articles) with your logo and backgrounds, and the app serves a 1200x630 image for every link. Most themes print their own share image first, and social networks take that one. The dashboard checks your theme, lists the exact lines to comment out and gives you the corrected file to paste.
