Until Snapchat gets around to allowing users to delete people from group chats, users need to get creative to suit their needs.
One of the easiest ways to get around not deleting someone is to simply create a new group. This method works in your favor since you can add everyone from the old group except for the problematic person in question. As a result, your group members will leave the old group and join your upgraded group. It’s very petty, but it gets the job done.
This third method may feel like a last resort, but it’s the easiest way to avoid any drama: allowing the group to expire. Keep in mind, just like regular snaps, group snaps will expire and eventually delete the group after 24 hours.
