I have a BLU cellphone and on this device WhatsApp was installed.
Today, 14th of March 2016 I received a message that the current version of WhatsApp was not working anymore and I should download a newer version.
So I did. First I've uninstalled the other version and than I've tried to download the newer version.
Now I receive the message " This app is not available I your country".
What can I do to re-install WhatsApp on my cellphone?
