You can switch the public setting of your store at the "Shop Settings" on Mypage.
If you set your shop to private, all products in your shop will not be shown to the public even if the products are individually set to public or limited public. If you set the shop back to public, the product's public status will be applied.
Also, you will not be able to receive dividends from child product while your store is private.
For details, please refer to "What is a dividend from child product?" for details.
