Shopify SEO and Optimization Specialist

I have a 2 month old Shopify store. The Dutch version is on the .com/nl page of the site: www.italianbraceletshop.com/nl Google.nl example keyword: italian bracelet This is also the most important page. I was ranking top 20/30 for keywords. However now I am completely out of the serp, not ranking anymore for any keyword. When I do a site:italianbraceletshop.com search the most important page (/nl home page) is not even showing anymore. The .com and multiple /nl/ pages are showing, but not the most important page. Everything is set correctly. The href lang settings, canonical url set correctly, google console says indexable showing right canon url, there are no bad signs or bad settings. I am really looking for an expert who knows what is going on and has a plan of how you are going to fix this. Please understand general replies won’t be considered, only seo specialists talking about this specific situation.
