@orizens Hey man. So the scroll up feature is still very buggy. The calculations are very wrong.
You can test on your own demo, just try for example a big screen (2k resolution), scroll down a little and then try to scroll up, you will notice scroll up event does not fires. It only fires if you scroll a lot down and then up.
This is a bug in the calculations you are making, because for example in my case I don't have any scroll down to make (chat app) and when I scroll up it never fires the event.
Is it possible for you to take a look into this issue please?

Also experiencing buggy behaviour on scrolledUp event. I need to set infiniteScrollUpDistance to 9.5 for it to fire.

Is there any solution to solve this problem?

Having the same issue. It can be reproduced on the demo stackblitz: https://stackblitz.com/edit/ngx-infinite-scroll?file=src%2Fapp%2Fapp.component.ts

FWIW ( and for those that might be looking for another solution ), I've been able to build my own infinity scroll, with minimal effort, using the new Angular virtual table scroll
