Invite to Game option is grey on everyones profile

Check your privacy settings and that way you will be able to change any setting that prevents you from inviting other gamers in parties.

Hello! Have you tried a hard reset?

Steps:

1. Press and hold the power button on the front of the console until the Xbox One completely shuts down
2. Once the indicator lights on the front of the Xbox One and the console’s power brick are off, disconnect the power brick from the back of your console
3. Wait at least 5 minutes
   
4. Plug the power brick back into your Xbox One and turn it on

Do you have an active Xbox Live Gold subscription, Dylan? To play a paid online multiplayer game on Xbox, an Xbox Live Gold subscription is required. To check, please follow the steps below:

"Press the Xbox button on your controller to open the guide, and then select System > Settings > Account > Subscriptions."

Ok, right I've asked everyone to check their online status and NAT and everything is ok on their consoles. It simply has no option to invite anyone to a game lobby who are playing on an Xbox one and will not show them as online in the game lobby itself yet
it does show them online on the Xbox one dashboard but the heading invite to game is greyed out and unavailable. Think this needs an update to sort it
