Truecaller's caller id feature not working!

[Amit Mishra3]

Bought Lumia 640 XL today.. Installed true caller but it's caller id feature isn't working... Its saying to update"extras n info" and "network +"... Iv updated extras n info but there's no update available for network+...what should I do? I'm pretty sure updating network+ will resolve it cause this happened with me in my L620... But what should I do when in store it isn't showing any update for network+
PS I'm using win8.1, moved it to phone memory, n I have denim...

All it ever did, for me, was load up my contacts with a slew of entries and then never did anything further.
