I'm unable to re-install Whatsapp as the iTune Store keeps appearing the terms and condition, once i click the iTune Store. While on the term T&C page, there's no button for proceed. Cant do anything. Has anyone experienced it ?

Hi umawi,

I understand that you are trying to reinstall an app from the App Store, but you are unable to accept the new Terms and Conditions for using the App Store. I have a few suggestions for you that may help you resolve this issue. First, I would like to recommend that you restart your iPhone and then see if the issue persists:

Restart or reset your iPhone, iPad, or iPod touch - Apple Support

If the issue is still present, try clearing the Safari History and Website Data, which is explained in the following article:

Safari web settings on your iPhone, iPad, or iPod touch - Apple Support

To clear your history and cookies from Safari in iOS 8, tap Settings > Safari > Clear History and Website Data. In iOS 7 or earlier, tap Clear History and tap Clear Cookies and Data.

If it is necessary to take the above step and clear Safari information, you may want to restart the phone again before checking to see if the issue is cleared. Thanks for using the Apple Support Communities!

Cheers,

Braden
