If you’re an online store owner, and especially a Magento 2 store owner, it shouldn’t be unfamiliar to come across a situation in which you find it hard to provide the customers with equally detailed and sufficient information about the product that you’re selling. Sometimes, the product is complicated and it requires an equally detailed description in order for the customers to see, to consult, and then to make the purchasing decision. Providing you couldn’t provide them with enough information about the products, it’s highly likely that they couldn’t understand them and as a result, choose not to buy them.
An idea here to serve the customer who is actually interested in your products is to offer them attachment files, but the default setting of Magento 2 hamper you from doing this. This creates a lot of inconvenience for your online store on Magento 2.
