When I create a new contact through the iPhone Phone app, the contact is successfully saved to my Yahoo account and is visible when I sign in to Yahoo Contacts online. However, the contact does not appear in the Contacts app on my iPhone.

I have already completed the following troubleshooting:

• Confirmed that the correct Yahoo account is connected to the iPhone
• Confirmed that Contacts syncing is enabled
• Turned Yahoo Contacts syncing off and back on
• Removed the entire Yahoo account from the iPhone
• Restarted the iPhone
• Re-added the Yahoo account using the built-in Yahoo account option
• Confirmed that the missing contact remains visible in Yahoo Contacts online

The issue continues after completing Yahoo’s recommended troubleshooting. Please escalate this as a Yahoo Contacts synchronization issue and advise how the server-to-iOS contact sync can be reset or repaired.

This problem is causing contacts that I save through my iPhone to appear to disappear from the phone even though they are stored in Yahoo online.
