I am trying to test Xbox Live on my UWP game but when I goto My Developer Dashboard and open Services -> Xbox Live and press "Test" to publish my changes to my sandbox I get the message "Publish Failed" with no additional info or explanation.
I have gone in circles with this for days and I cant work out what I'm missing. Please help. I don't know what else to write and I do hope this isn't seen as low effort If anymore info I can provided could help please let me know.
