It is very very often. Even now I have this problem. And not only I have this problem, because @virtus4 had this problem too.
[BTW, there is another bug and I was not able to publish this comment on Ecency (web version), and I had to use another interface]
Could you share a link to a post where it happens?
I do not understand what link...
Maybe I'm the one not understanding! Could you explain the actions you are taking regarding the friends feed refresh so that devs can try to recreate it?
I just scroll down. A new post appears for a second. And it disappears and instead there is an old one at the very top.
Do the new posts appear below older posts, or new ones just disappear
Just like this. They appear on 1 sec and then I see only old posts.
Also,
What error message did you receive?
