Thanks for the feedback. I agree that hitting a loading spinner on the home screen should never happen. Sounds like you might have encountered a cold start. Occasionally the Android OS will kill our process to relieve memory pressure. This tends to happen when you are using an app that consumes a lot of memory in the foreground and then return to Home. Improving our cold start time and adding additional protections to our process to make it less likely to be killed are things we're working on. We're also continuing to tune our ranking algorithms for showing you the freshest most interesting content when you turn the screen on. The fullscreen experience of Cover Feed presents some unique and interesting technical problems to solve, but our goal is that the most relevant and fresh content is always given the highest priority. We'll continue to tune this over time and fill in missing features. We'll be making some blog posts about the engineering of Home soon that will go into more detail on some of these areas. Thanks for your patience on the wider rollout. I'm really excited to get this in the hands of more users.
