Fix iPhone Contacts Not Syncing with WhatsApp

So, what could be preventing your iPhone contacts from syncing with WhatsApp? At the heart of this malfunctioning syncing issue could be the wrong configuration. In trying to amp up the privacy game, you might have restricted WhatsApp from accessing your iPhone contacts. That aside, a software glitch could also be coming in the way and hindering your contacts from syncing with the Meta-owned messaging app.

1. Ensure That You Have Not Restricted WhatsApp 

To begin with, make sure you have allowed WhatsApp to access and use your iPhone contacts. 

  • On your iPhone,  open the Settings app > Screen Time > Content & Privacy Restrictions.
  • Now, ensure that the toggle for Content & Privacy Restrictions is enabled.

2. Ensure That the “Privacy & Security” Setting Has Not Limited WhatsApp

Another essential thing that you must do beforehand is to ensure that the “Privacy & Security” setting has not limited WhatsApp on your iPhone.

  • On your iPhone, head over to Settings > Privacy & Security > Contacts > WhatsApp and choose the Full Access option.
  • Now, open WhatsApp (If the app is already opened, force kill the app and launch it) and check if your contacts have started to sync with the messaging app.

3. Update WhatsApp on your iPhone

If you still cannot sync your iPhone contacts with WhatsApp, try updating the app as an app-related bug could be causing the problem. 

  • On your iPhone, navigate to the App Store > Tap on your profile at the top right -> search for WhatsApp and then update the app. 

4. Update Your iPhone

However, if nothing has worked in fixing the contacts syncing problem with WhatsApp, update your iPhone as there is a high chance that an iOS bug could also be spoiling your party.

  • To update your iOS device, fire up the Settings app -> General -> Software Update.
