> Do you see the same contact on the iCloud website?
No. I wasn't trying searching in other devices, only in iCloud.
What's in iCloud that's in other devices; sync from iCloud is correct.
I see that that recreated contact in my iPhone 7 plus is not in iCloud search results (also OS X) but it is in my iPad Mini 4.
Just to verify, I created a new contact in my iPhone with the name "Lorenzo" (the string for searching).
It is synced to the iPad, not to iCloud (so OSX-iMac).
I repeated the same from my iPad and the contact was uploaded to iCloud.
Then I created a similar new contact from iCloud. It is synced to all devices.
I had said a contact added from a whatsapp vcard someone sent me some weeks ago and it was synced to iCloud I repeated the procedure asking a friend to create a contact containing that string and send it to me via Whatsapp.
From Wsapp -> Contact details -> Create New Contact -> Save
This time this contact was not synced to iCloud.
Summary: iPhone new contacts are synced to iPad but not to iCloud
Checking iPhone Settings -> Contacts -> Default Account I have 2 Gmail accounts and iCloud. It is the third time I had to check iCloud (previous were 2 and 3 weeks ago). I don't know why it changes to one of the other 2.
Sorry, now I realize why was that: one of the tests was to switch off Apple ID -> iCloud -> Contacts. So Default Account changed to one of the existing gmail accounts.
Anyway, after a while sync to iCloud is not performed.
All tests/devices were under the same network.
> Regarding your WhatsApp contacts, if I understand correctly, you're using the "Add to Contacts" function from within the app, and the new contact doesn't appear in either your built-in Contacts app, other devices, or the iCloud website. Is that right?
It is saved to Contacts but as the other ones it is not synced to iCloud.
> do you have any WhatsApp updates available in App Store > Updates?
I've set to manually make apps updates. I get a notice from Settings when an app update is available. Wsapp is up-to-date.
This issue is beyond Whatsapp, I guess.
Thanks a lot!
