My Whatsapp profile picture isn't showing, how do I fix this?

I have an iPhone 6 and have tried to change my profile picture on whatsapp but it is not reflecting on my contacts whatsapp's. It appears on my own whatsapp though.
How can I fix this?

Whatsapp support still hasn't replied to my emails.
What do you mean it is not reflecting on your contacts? Can you clarify please?-
My contacts are unable to see my profile picture. On their whatsapp, my profile picture is blank.-
Thank you so much! It is exactly that. You are a lifesaver Ollie!-
My photo is not showing on whatsapp-

I did a little bit of research and it seems to me like there are a few things that could be causing this. If it is multiple people that cant see your profile picture it may be their settings otherwise it could be your own privacy settings.
Reasons your profile picture cant be seen according to Whatsapp:
- The person has changed their privacy settings to "Nobody"
- The person changed their privacy settings to "My contacts" and you are not saved in the person's contacts.
- You are blocked by the person
- There is a temporary network issue
- YOU HAVE CHANGED YOUR "PRIVACY SETTINGS"

I left the last one in capital letters because to me it seems like that may be your problem so I would try and take a look at the privacy settings on your Whatsapp account.

Step 1: Open the Whatsapp app
Step 2: Go to the menu button
Step 3: Click "Settings"
Step 4: You will see a little pencil, click it
Step 5: upload the same photo you want to have as your profile picture
Step 6: Then go back to your "Settings" and click "Account"
Step 7: Click "Privacy"
Step 8: Change the settings to "Everyone"

Tell me if this works, if not maybe I can try and help you again. Hope all goes well! Let me know.
