Always shows on my profile as me being in a party alone, but if i go to the party app i am in no party. My friends also see this and try to join and never get in because it is not there. Been doing this for weeks.
Resetting Xbox one and letting it stay off does nothing. problem comes back as soon as i leave a party again. or make one and leave it.
Also the achivements leaderboards are not updating properly for a while no as well.
