So this already made the rounds yesterday, but I couldn't find a news source in English when I think it still is newsworthy. The skinny is that for some reason iOS doesn't schedule updates for reported Corona infections. Reportedly, some installations haven't received infection data for up to ten days. I just checked, and my last updates (which I understand are supposed to refresh daily, for every day in the past couple weeks) were days ago. A similar problem also exists or has existed on Android.
