My Xbox won’t become interested in other people’s posts

In order to get other gamers' activity to appear in your activity feed (providing that they are gaming/posting activity) you have to make sure that you are "following" each of them despite being a friend of each of them etc.

Let me know if this solves the problem.

If you're having trouble joining Looking for Group posts, I'd recommend
reviewing this page under "How do I start using Looking for Group?" What error are you seeing? Is it the same group of people or from the same club that's having issues or is it across everyone? More information on your issue can help us troubleshoot
what the problem is.

Could you please elaborate where do you want to post and what happens when you try to send your post.

If you can write it better I might be able to understand what you mean 🤔

The activity feed has settings you can adjust at the top, the button looks like a funnel. You can also click the ... at the bottom of a post to choose some options of hiding or blocking that content. You can follow specific games and people at the moment.
I'm not sure how much AI learning is involved in our activity feeds though to customize our experience like on Twitter or Reddit.
