If I try to create a post, it always fails and says "There was a problem posting your Looking for Group."
And if I try to join one, it always fails and says "This post is no longer available."
I would give up and assume this game is not integrated with Game Bar, if not for the fact there are hundreds or thousands of Sea of Thieves Looking for Group posts per minute.
Windows and Game Bar are up to date, and I've removed all my firewall rules just to be sure.
How can I get it to work? I'm out of ideas, there hundreds of posts on Microsoft forums about this problem with irrelevant answers from Microsoft employees, and users advising to use Discord instead. I know Discord exists, looking for a way to use Looking for Group in Game Bar, which is obviously working for hundreds of thousands of other SoT players.
