With Signal, the biggest issue we have is that review times are extremely inconsistent. Sometimes it's 4 hours, sometimes it's 5 days, and there's no visibility as to why. Our working theory is that there's automated and manual queues, and occasionally, for whatever reason, we fall into the manual queue. But when you work on an app that has weekly updates, randomly getting hit with a review time of several days really throws off your groove. And it can obviously be terrible for moments where you're fixing a critical issue.
