LG G3 - uninstall enotify and revert to default software

[AC Question]

Hi there

I have an LG G3. I have installed e-notify but have decided I would like to go back to the default notification software that came with the phone. The "uninstall" option is not available on Google Play.

Can anyone advise me as to how I can get rid of enotify and go back to the default software?

Thanks!
