Why can't I add a friend to my friends list?

Hi there! Sorry to hear about that. Let's do our best to get this sorted out.

I just want to confirm if this is happening to a specific friend only or to multiple friends of yours?

Have you also tried to add your friend via the Xbox app on mobile and on the website https://account.xbox.com/Profile?

Please ask your friend as well to add you back as a friend.

Oh OK but when I went to add someone is on my friends list that is showing on my friends list on the Xbox app and it said that the person I tryed to add is already on my friends list. So why didn't show on the friends on my xbox 360?

I have found through the Xbox app for my android phone I have been able to add friends to my ingame friends list. also I have realized that to have friends that are on my Xbox friends list they have to be added to my Xbox 360 friends list to appear as friends
in my games. I do not understand why I cannot just add friends in game through the Windows 10 game screen.

My problem is that he isn't on my friend list. Due to a glitch of some sort, he was removed from my friend list after he blocked me and I can't add him back. I am on his friend list, but when I add him, it says "Sorry, we can't save your changes right
now. Try again in a while."

My name bio online status and friends list is only viewable on peps on my 360 friends list. Cloud us on my xbox 1 friend list but because of the system hes not on my 360 friends list cuz both our 360 lists are full. My parents taught me not to reveal personal
stuff to stangers thats why. What I dont get is since cloud is on my xb1 list why xbox.com says add friend he isnt a follower.
