Regarding the button for "import my addresses" which does not, in actuality, allow to import addresses. I am concerned that customers will try to upload a CSV to this button, as this is what one would expect in the customer journey. It is so easy for customers to get frustrated and leave the site- I am concerned we will lose sales because of this. Based upon this I also anticipate many questions from users for the website's customer service team, which will increase costs for the business I am building the site for.

An update suggestion would be to change the language of the button to "Access my addresses" or something along that line would be a better solution for the end-user experience. OR just create an option to import addresses (that would be the better option).
