Most Magento sites are selling physical products and not downloadable products… so I find it interesting that Magento’s default behavior is to show a My Downloadable Products link in the Account Page by default.
There is no way to disable this via the admin… and it is an irrelevant option for most use cases.
There are various Stack Exchange articles on the topic providing the coded solution for this, but I just find those solutions inelegant.
Enter magepal/magento2-customeraccountlinksmanager, a composer installable extension that provides a simple admin interface to control which links appear in your customer account page.
With this extension not only can you remove the My Downloadable Products link, but you can remove any link you want! And the best thing is… it works!
