This is not to detract from development progress when there's already too much work, but I'm not sure the "throw bugs over the wall" approach is getting all the tester feedback that would best advance the Mobile project. Perhaps I'm uniquely stymied by Canny or something, but personally I just have no sense of what's been reported, what's fixed, what's in queue for re-test, etc. That's in stark contrast with server-side feature development, where I find that team's weekly user group helpful. There may be an easier or more effective approach than a user group (which is always inconveniently scheduled for somebody), so it's just one example that might help.
