Created a Whatsapp group, then left did not get message to delete group
If you were the only group admin and you exit a group, a participant is chosen at random to become the new admin1. The new admin can then remove each user individually or the rest of the users can voluntarily leave the group like you did. You cannot do much at this point since you are no longer an admin in the group.
