Why isn't true caller supported for Microsoft 640 XL?

[WPCentral Question]

true caller not supporting for Microsoft 640 XL

I go the settings to enable it, switch on by sliding the button, it takes me to a prompt box which says allow truecaller to identify contacts not in the contact list. I press ok but when i return to the app, the toggle button automatically is set to off again. It doesn't activate at all. I repeated this process several times but it switched off on its own again and again. I've tried uninstalling the app but with no luck. Is anybody here facing the same issues? I have installed app in phone memory only Help is needed. Thanks in advance.

Perhaps in the Settings/Privacy/Contacts, TrueCaller is disabled?

I'm also facing the same problem. I have checked true caller is enabled in settings >privacy>contacts
