WhatsApp was having issues on Windows Phone 8.1 and due to that WhatsApp removed from Windows Phone 8.1. Searches for the Whatsapp on handsets running Windows Phone 8 or 8.1 showing “We couldn’t find a match. Try a different spelling or search term.” WhatsApp said that we removed this app globally but we will come soon with fixes.
We don’t have the actual reason why Whatsapp was removed from the app store. WhatsApp was working fine on both Windows Phone and WP 8.1, may after Official release of Windows Phone 8.1 Whatsapp will take the fresh start. WhatsApp chosen to pull the app until they get it updated. It is better to not be there at all than to leave users with a sour taste in their mouths.
Those who are using WhatsApp on their WP device then its fine otherwise you need to wait until WhatsApp has finished “working closely with Microsoft to resolve the issues”, we would not expect to see the app returned to the store for download. This the message WhatsApp is giving to their users:
"Unfortunately due to technical issues, we have chosen to un-publish WhatsApp Messenger on the Windows Phone platform. We are working closely with Microsoft to resolve the issues and hope to return to the store shortly. We apologize to our users for the temporary inconvenience."
We will try to give more and quick updates about latest technologies, gadgets and more in time, also keep connected with us to be the first to know about the availability of WhatsApp on Windows Phone App Store.
