I took a look at your account and everything looks healthy on the backend. You have 50 subscriptions, all actively polling, no errors. Right now you have 156 unread stories which is right around your expected 150+ per day.
Since things look normal now, my best guess is that you were temporarily in Focus mode without realizing it. You have 4 feeds trained with Focus (green thumbs up on the feed itself): Laughing Squid, xspeeds.eu, Charlottetown Police, and one other. If Focus mode gets toggled on, you’d only see stories from those specific feeds, which lines up with the “6 stories from 4 feeds” you were seeing. On the iPad app, double check that the filter at the top of the feed list is set to “Unread” and not “Focus.”
Two other things I noticed:
1. Boing Boing hasn’t had a new story since March 6. The feed URL is an old FeedBurner link that may have gone stale. You could try deleting and re-adding it with the site URL boingboing.net to pick up a fresh feed address.
2. The login prompt you’re seeing is from TV Chaos UK, not from NewsBlur. That site requires authentication to access its RSS feed. If your credentials changed on their site, the feed will keep prompting. You can update the saved credentials in NewsBlur by going to that feed’s settings (the gear icon) and entering your TV Chaos UK login there.
Let me know if the unread counts drop again and I can dig deeper.
