This is the category “linux” in my tt-rss
As you can see, “Phoronix” feed is separated. “Tiny Tiny RSS” are inserted between.
Such things occurs periodically with different feeds.

Include steps to reproduce the problem:
I would like to help and reproduce this issue, but I’m not sure how. Is there anything that would be helpful?
I can provide a DB dump with the issue on the screenshot.

In Preferences uncheck “Group by feed”. I think you can also do this with the keyboard shortcut f g.

But i prefer “Group by feed” enabled. I prefer reed all articles in one feed and then in another feed

If i uncheck “Group by feed” then i get the same problem with one feed between other feed. But, I believe that in this mode, this behavior is correct

this is working by design, based by article timestamp. search this forum, this has been discussed several times before.

e: Search results for 'yyiw' - Tiny Tiny RSS: Community

Then only select that feed, rather than the group containing it and other feeds.

Or don’t let articles get so out of date before you read them that they get split, by design, in that fashion…

If is working by design, then ok

p.s.
It is not very convenient and not logical. Articles sorted from the oldest to new.
But on my first screenshot it is clear that the new article is located above the oldest.

I am quite sure that there was no such behavior before, it appeared after some old update long time ago.
I thought I had problems with the database.
