I often answer questions on StackOverflow on specific topics. Today morning I had one specific feed with ~60 messages, I’ve looked through it, and decided to answer some questions from few days back later. But one hour later, the same feed was cleared to have only data since yesterday, and all previous messages have gone. I’ve noticed the same behaviour for another feed, but not for all.
Why this may happen & how it could be prevented? Because for it’s a data loss.
Looks like you’re hitting feed limits. Right-click on a feed title and open Statistics. That will show you any messages about what upgrading might do. To preserve all stories in a feed, you’ll want to upgrade to the Premium Archive subscription.
Ok, I just released a fix for a different thread but it concerned the number of stories visible, so I have a feeling it should fix this as well. Let me know if that’s not the case, and please include screenshots if you can so I understand better what you’re seeing.
I suspect the same is true of these other feeds. I’ve exposed how many stories are in the archive, but the statistics dialog shows the history of stories fetched. They aren’t all retained. If you want them saved, you’ll need to upgrade to the premium archive tier.
But I haven’t changed the story cutoff number when I launched premium archive. But I change it all the time to account for how much storage certain types of feeds take, so there’s no guarantee of hundreds of stories on a single subscriber feed that publishes less than once a day.
I interpreted the OP to be talking about unread counts, but reading back he never actually said that. Possible I actually have a different issue. But yeah, I had some 30 unread stories over the past month (out of roughly 400) that I was going to go back to, and they’re marked read now. Same goes for Polygon. I do understand that stories are automatically marked read at one month on my plan.
