I have an older android phone (HTC wildfire). Runs the original Android operating system comes with the phone (2.2 I believe). Whatsapp was working fine. One day, a message appear to ask me to "update Whatsapp". Tap on it and proceed to download, it was downloading and when it was done, it said "update fail". I tried multiple times, the same thing. The network connection is fine and I have tried downloading other apps and it was fine. I turn off and turn the phone back on. It was still not working. I uninstalled Whatsapp and tried to download it again. Now, whatsapp is not even showing on playstore for me to download. Any ideas would be appreciated. Thanks.
