Hi Tory,

Thank you for reaching out. We've removed the direct CSV upload functionality as we have some exciting new functionality in Beta and Private Preview that we replace it in a better, more flexible and easier to use way.

Our new Magic Folder functionality allows you to pick a single folder in one of a number of file storage systems, in order to sync a new CSV file all you would need to do would be put it in that 'magic folder'.

We are in beta with this functionality for Box, Dropbox, Google Drive and Private Preview for OneDrive and SharePoint. Would one of these services work for you? If so I'll be happy to invite you to start trying it out.

Alison (Product Manager)
