I'm unable to sign-in into http://circular.io/

[twi5]

When I click "Sign in with Twitter" on circular home page, it redirects to twitter oauth page. There I click "Authorize app" then it redirects to circular home page http://circular.io/ with an option to "Sign in with Twitter" instead of "tweet scheduler box". And there is a circle in center which keeps revolving infinitely. Every time I try to sign-in, this happens again and again.

Please guide me to resolve this problem.

Thank You

+1 I'm also having difficulty signing in months later it seems. I tried revoking access and adding it again, but no luck.

Same here. Worked fine for about a month then unable to sign in. Been monitoring it for about another month and still not fixed.

Same problem here. Been broken for months. Other accounts work, but this one particular one is stuck.
