Why is my WhatsApp profile picture not showing

IT HAPPENS TO ME TOO. IT HAPPENED TO ME ON APPROX THREE OCCASIONS IN THE LAST MONTHS. SO I SENT MAIL TO THE WHATSAPP HELP MAIL, BUT THEIR ANSWERS WERE THE SAME AS COMING ON THE INTERNET FROM THE PRIVACY SETTINGS.
If you can’t see the last hour Once a contact’s profile photo, info. or status updates, or another contact can’t see your information, it could be for one of these reasons:

The user changed their privacy settings to “Nobody”.
You changed the privacy setting for your last hour. turn to “Nobody”.
Your contact changed their privacy settings to “My contacts” and they don’t have you saved in their contact list.
The user blocked you.
There is a temporary connectivity problem.
Your contact doesn’t have a profile picture.
Your contact hasn’t posted a status update.
Both have to resynchronize the contacts.

THE LAST THING I DID WAS SYNCHRONIZING MY CONTACTS, IN THE CONTACTS SECTION OF WHATSAPP, IN UPDATE.
AFTER THIS I WAS ALREADY SEEN MY PROFILE PHOTO.
I DON’T KNOW IF IT WAS BECAUSE OF THE MAIL THAT I SENT TO THE HELP OF WHATSAPP OR BY THE UPDATING OF MY CONTACTS. OR MAYBE THE TEMPORARY PROBLEM IS ALREADY SOLVED AND IT WILL HAPPEN TO ME AGAIN IN TIME.
