Has anyone been able to login to the app? The sign in button does nothing when I click on it, and the sign in link in the "default chat" just takes me to a blank page. It's been like this for 2 days now. I'm somewhat assuming it's a weird regional behaviour...my Apple account is based in Canada but I am physically in Europe. Is this not available in Europe, and it's tripping out since I'm connecting from a European IP?
