Stuck on "Online status unknown" and can't receive invite notifications on the Xbox itself.

This is an ongoing issue unfortunately, and Microsoft is working on it. Check for status updates on the Xbox support twitter page. Good Luck.

Hey there Josh!

Sorry to hear that you were experiencing this issue that stemmed from our service outage.

It seems like the outage has cleared as per the website and twitter, so if and when you can, power cycle your console as outlined in

How to restart or power cycle your Xbox One console
and make sure the problem has cleared up.

Thanks for your patience and for reading!

Ok thanks. Is there a link to this twitter account?

There's a current bug that seems to be going around sending and receiving game and party invites through Xbox. All of my friends play on an Xbox One. About a day ago I tried inviting a friend and they weren't receiving the invite notification on their Xbox but were receiving it on their phone. We have tried restarting our WiFi and our Xbox but nothing seems to work except joining their open party with online mode on. I don't know if this is a known bug or is new and unknown.

If anyone has any solutions that'll be great.

Yes i have the same problem i see i do get invites on my phone but not appearing on my xbox. I can only invite people i dont see friend rewuests but i see them in my notifications tab. But invites cant be found now i know others have the same problem
