Activity feed won't show my achievements when I unlock them for 70 days now

It wont "fix itself" i unlocked 4 or 5 achievements in san andreas about 6 days ago and none of them are showing as unlocked and when I go to my feed on another profile, it wont show some achievements. Im not appearing offline and i tried deleting and redownloading
my profile on both 360 and xb1. The activity feed is broken and im extremely angry at Microsoft. This shouldn't even be a problem. Im tired of wasting my time getting this to work and im about to cancel my xbox service and get a ps4.

This is still an ongoing issue. My achievements have not appeared since October 23rd automatically on the activity feed. My achievements do unlock but they just don't show up on the activity feed automatically.

Now the most recent activity in my feed is from 50 days ago. But the screenshot I set as the showcase is showing as the showcase. Also I unlocked an achievement in the Twitch app today and it's nowhere in my achievements when I view my profile. Something
is seriously wrong here. Would be great if support staff was looking into this. From what I'm reading it seems to be a widespread issue.

Thank god I found others hving the same problem and its not just me.. I am having the same problem for about a week now.. Mostly the same as the people above, my activity feed is broken, showing achievements from 14+ days ago when I have unlocked achievements
since.. then upon refreshing or coming back to the feeds tab, sometimes it will show most recent achievements from 7 days ago, 20 days ago at the very top when I have unlocked some achievements since then, my "Showcase" is also broken.. It is empty and I have
had stuff on my showcase, When I try to click on it nothing happens, it just says

"It is your showcase, so brag a little.. Look for the share button in your game clips, achievements, and activity feed." so when I go and try to share something to it sometimes it will either say shared! or it will say sorry something happened please try
again in a while with a sad face but when it says shared I go look and nothing is there at all.. I have tried hard cycling, removing my account, unplugging my router and power brick from the xbox, even reset to factory settings while keeping games and apps.
I hope this gets fixed soon because I enjoyed the showcase and the activity feed.

Now it's went from a broken feed to occasionally no feed at all. I see activity from one person out of 30 or so on my list. Leader board is wrong. Showing people online when their off. Feed is days behind at this point. Not showing achievements or clips.
Only thing that shows is one person when they add a friend. Weird.
