Deploy with balena button does not work

Hello balena-Community,

I am currently new to balena and balenaCloud. I tried to relize the balenaSound project (Getting Started | Balena Sound) and clicked on the button “Deploy with balena”. According to the manual my balenaCloud dashboard and little pop-up (see below) should appear. But everytime I click on this button only the dashboard loads with nothing else. Did I miss something?

Kind regards,
Tedwayler
