Describe the problem you’re having:
If I group headlines by originating feed (keyboard shortcut f g) and select the main category in the left pane, at first the articles on the right are from the first feed. If I scroll down, at some point, articles from the second feed are shown, but leaving unread some of the previous one.
…
If possible include steps to reproduce the problem:
group headlines by feed, click on the top category, and scroll down.

In this screenshot, as you can see from the favicon, the top unread article from the left belongs to the 4th feed and there are unread articles in the 1st, 2nd and 3rd feed
I noticed this happens when I read newer articles (on my smartphone) leaving older unread. It seems that it somehow breaks the “internal cronology” of articles.
I also noticed that if I would read all the articles in the order proposed, it would eventually show me the missing articles from the first feeds
Oh, and by the way, merry Christmas everybody

articles are grouped by week (or a similar interval, i don’t remember exactly right now), so it can go feed A, feed B, feed A again, etc, in batches
it has been discussed on this forum already
You are right and I should have search before posting. Sorry.
In my defense, this behaviour is only happening when you start accumulating lots of unread posts, which does not happen to me a lot. That’s why I did not occured to me it was inteded.
I believe this is the situation where I would prefere to be able to go through all the articles of the same origin, without mixing them.
But I guess it is enough to read feed by feed, instead of using the category.
