Can't change or assign group admin
If you’re a group admin, you can make a group member an admin.
If you’re unable to make another member an admin, it might be because:
- You’re not a group admin.
- You and the member aren’t on the latest version of WhatsApp.
- The member is already an admin.
- The member is no longer in the group.
- There’s a network issue.
Note: WhatsApp can’t interfere with group administration functions. For example, we can't make someone an admin.
