I just logged in to fb (Android app) for the first time today and was shown a post shared by a friend. I left a commmment and was shown a weird message "will be shown once online". Never seen it before, but no problem I just need to check my comment went through. Too bad! That shared post is no longer in my feed, even after dragging to refresh 3 or 4 times, each time showing completely different content, mostly stuff from previous days that I had already seen (but I still have to scroll for ages to check because what was on top might be down lower now). In the end I had to go to his fb page and check manually, because the algorithm that decided that post was important immediately changed its mind on my behalf.
PS: the comment now appears on some refreshes and not others.
