Hello @LindavidM ,
Make sure to check your Import/Export page in your Contacts, and select the file type you wish to download. If you have issues with downloading that export, I'd advise accessing the site on a normal laptop/desktop, as some of the site's functionalities aren't compatible with mobile devices.
