There are things in my Activity feed that I cannot see or delete, but others can view them

Thanks Quimby, I can now post to the activity feed. I cannot however see my activity feed on the xbox one dashboard. How do I get it back? As said, all I can see is what my friends are playing and the leaderboard, there's no activity feed.

I have, verbatim, the same issues. Additionally, when attempting to view my own videos on the Activity Feed 90% of my clips stop as if they failed to load. I cannot delete old clips in the Captures tab of my profile, either.

did you get the problem fixed? I am also experiencing a problem with the lack of activity feed. I cannot see any of MY activities nor any of my achievements etc. but I CAN see activity feed of only ONE of my friends on my friends list and nothing for the
rest of my friends.

In my experience Blocking them does not remove them from your list they simply cannot see anything you are doing or post to your activity feed

Perhaps I am not being clear.

I am looking through my activity feed. I click on a screenshot that someone else has made. However, I cannot see the entire screenshot. These screenshots (from other users) were taken on an Xbox, but in the Windows app, it does not properly scale them.

I have no issues on the iPhone app or Xbox itself. Only the PC app when browsing the activity feed.

I am not referring to my own captures. This is an issue when I try to look at anyone's captures in the activity feed.
