App Update Reviewal Urgently Needed

I've sent out an app update to fix our login issues and even requested for an expedited review. We're now sitting on day 2 of waiting in review and no solution in site. Our users are dropping off and new users just cant login. It's a minor bug fix that we need to push out. Anyone know whats best way to get the review faster apart from expedited app review requests?
