I’ve tried both in Chrome on windows and Arc on MacOS. Whenever I click deploy (either straight or Custom) it kind of refreshes the contents of the page again, closing any deploy process like nothing happened. It starts to deploy but the top loading bar on the page is loading like it refreshes the page.
My account was locked, had to authorize the payment method. Strangely enough that was the reason, but the UI itself didn’t say anything nor redirect to the page with the problem, nor did it show the Red bar on top warning, as it does on the normal dashboard. FYI!
