Profile activity feed posts disappeared after deleting some posts and haven’t return after months?

This must be the eighth time I’ve made this post and searched for an answer and or solution to this issue I’m having.

About a month ago I was deleting achievement posts off of my activity feed as I wanted to use my activity feed to share things I deemed important such as screenshots, certain achievements, and posts for me and my friends.

There were years worth of posts and I wanted to sort through which to keep. After deleting for about 15 mins, suddenly they all disappeared instantaneously. I didn’t delete them all as I kept checking and knew there were lots left.

I’ve tried countless things such as refreshing the page, making new posts, simply waiting but they still haven’t returned. I’ve also searched forums, tried to contact ms support, and asked elsewhere and got nothing.

I cared a lot about some of those posts and really want them back on my activity feed.

I’d really appreciate any help anyone can provide.
