We all know that WhatsApp has replaced the custom of text messaging and made our life easy to communicate. WhatsApp is available with almost all mobile operating systems. As far as Windows Phone is concerned, WhatsApp team has introduced some nice features, for this OS, which was earlier available for Android and iOS users only. WhatsApp by default makes a backup database of your messages periodically and thus using this database, you can restore the chat conversations.
However, in Windows Phone, there is a native backup option inside the OS itself and it helps you to save your settings, app stuff to cloud. Now due to two backup sections in the same phone or same OS, one may contradict with another. As a result of this contradiction, you may face the issue of WhatsApp tile being greyed out or the app becoming malfunctioned. Hence the app is no longer working and you can’t open it at all. If one message you during this scenario, he/her will get a sent receipt but still you won’t receive the message.
