My WhatsApp is not working. It's need to be updated but it's not getting updated as since yesterday. I'm downloading it out but it's not getting updated. I'm really worried now because there's a lot of important data stored in it. I tried downloading it over and over again but it's not getting updated. I also tried to uninstall it and reinstall it from goggle play store but it's refusing to be reinstalled and upgraded. All I can say is that my WhatsApp is not working.
