Groups?

If you open up 'My Games & Apps' and go into the Groups section. There's a option listed under More options that says "Delete all groups". When you select Delete all groups, you'll be shown an option to "Delete local groups". Deleting the local groups will
have the system resync your previously saved groups. When you're experiencing missing groups. This is the best method to return the missing groups onto your system.

If you've not already tried Deleting your local groups. I'd suggest giving it a shot.

First open up 'My Games & Apps'. Proceed to go into the 'Groups' section and then scroll down to the 'More options' section at the bottom. Proceed to then select 'Delete all groups'. You'll be shown the options to 'Delete all groups' and 'Delete local groups'.

Deleting local groups will remove and then resync your groups information stored in the cloud. Deleting all groups will delete the groups saved on your local console and within the cloud as well. You should then be able to start from scratch with how you
setup your groups..

To resolve this issue, disconnect from the last group you joined and try to join the new group. See how:
Go back to the last group you joined.
Scroll to the bottom and select Leave Group.
Try joining the new group again.
Note If you were the leader of the last group, the option to leave the group will not be available. To disconnect from this group, follow these steps:
Press the Xbox  button on the controller to open the panel.
Highlight the group, press the Menu button  on the controller and select Leave.
Try joining the new group again.

Thanks for the info on the clans.

For groups - if you search for a group and it doesn't exist it will prompt you to create the group. So just use the search function if you want to create a group.
