What happened to Allen here sucks. I've messaged the team so we can dig into this specific case. More generally, we know that Slides needs to be bulletproof when presenting, and nothing less than that is acceptable.
As an FYI, we _do_ use Figma Slides internally for pretty much everything, from internal meetings to major events. As a PM I use it every week, and our internal feedback channel for Slides is super active with folks like me requesting improvements. Figma is also a pretty unique place, where it's more likely our senior leadership request quality improvements than chase for deadlines - we know how critical the user experience is. We don't always get it right, but when we don't we're committed to fixing it.
