Why doesn't True Caller's Live Caller Id work on my Lumia 640 XL LTE?

[Windows Central Question]

why true caller's live caller id doesn't work on my lumia 640 XL LTE?

When I try to activate live caller id of true caller ,it says- there is some problem activating live caller id due to your network+ app and system apps...

Please resolve...

Firmware of lumia 640 LTE does not support live caller ID. It will not work.

Well it works for my L640 so it should work with the XL as well. Where have you installed it.. On phone or sd?

640XL has a problem with its software making few applications not work as expected. Reinstalling the software through recovery tool does the job. I fixed it that way and it works now.
