Canva has 3 options for how you can upload your work--WeTransfer, FTP, and a shared folder on a cloud drive service. Which one do you use? Have you tried using them all? Is there an appreciable difference between them in regards to response and ease of use?
I liked getting a receipt from WeTransfer when the file had been downloaded, but I currently use a cloud service because it's more organized. However, I might go back to WeTransfer so I can get some kind of an update as to the status of my uploads.
