Cloudflare Pages - Long Running Build

I know Cloudflare Pages is still in beta but just curious if anyone else has run into an issue where a deployment pulls in the repo successfully but then the job continues to sit and not proceed to build? I’ve run into this with a deployment of mine and don’t see a way to cancel the build.

Is there a timeout period set? It seems to be consistently happening on one particular repo I was testing with. The only way I can seem to get around it is to completely delete the project in Pages, wait awhile and then re-add it. Even this sometimes results in the deployment to get stuck and continuously run.
