Integration with Canva

The integration with Canva does not seem to be working with my account. If I start a draft email campaign, I don't see the option to create in Canva. If I go to the Library and create in Canva, nothing happens when I hit "Publish" in Canva. The design does not download to my account. I have to manually go to Canva first, create the design, download it to my computer, upload it to Constant Contact and then I can use it. That's not integration.
