Hello everyone,
It looks like I can’t clone a Showcase. No matter what name I try, I get “That subdomain is already taken, Try a different one”. Does anyone know how to fix this? Thanks!!
I’m also having this problem, really frustrating. Probably worth raising it with Webflow support.
Resolved! All you need to do is verify your account again via email, you can click on the banner at the top of the dashboard to send the email again 
I don’t have a banner above the dashboard. How can I re-request a confirmation email?
if you can’t VERIFY your email, close and open again webflow tab, and on the top of dashboard page will apear banner
