How do I delete a group?

At this time, there’s not a way to delete an entire Group. You’re able to remove individual people from the Group and then remove yourself. 
To do this:

1. Tap on the three dots next to the chat tile 

2. Tap on Edit Group

3. Remove each person by tapping on their name and selecting Remove from Group

4. After you have removed everyone from the Group, tap Leave Group to remove yourself from the group.
