I've been building an app hosted in Heroku, and until recently it's been working fine with automatic deploys from my Github repo, however recently it got stuck in the deploying phase and even when I deleted my app, started a new one, and hooked that up to my Github repo I got a "your build has reached its concurrent builds limit" error which makes me think there is a problem persisting somewhere, as when it got stuck deploying nothing appeared in any of the logs.
I've seen a bunch of commands on how to force stop a build however for various reasons I've been stuck working exclusively on the web and so can't have the Heroku CLI installed and those commands don't seem to work on the online console.
If there's any way I can get Heroku to cooperate that would be fantastic, as I'm pretty sure the error isn't with my code as I only added one small function that worked fine when tested elsewhere.
