Been "waiting for review" for several days, and support emails did not yet get a response. There is likely a staffing issue, or some other undisclosed problem with the review queue. I find it disconcerting that all of the language when signing up and submitting your first app is encouraging and states 90% of apps are reviewed in 48 hours. That clearly isn't true, and if something is preventing ours from being reviewed in a timely manner, we should at least be notified about it.
