When you have a free account and you read your feed folders it only populates two posts before ending. You then have to click on the folder again to be able to continue reading the remaining posts. It used to be much more, then it was reduced to 3 at a time, now today it’s 2.
It’s still 3, you probably just have a hidden story that’s not showing.
It went back to 3 somehow, any plans to return to the higher number previously. I realize it’s a free service, but the limiter seems arbitrary.
NewsBlur is a paid service. The free tier exists only as an unlimited demo.
