Doorbird app - push notifications for bell

Has anyone tried using the Doorbird app on a BB10 device? I have a Doorbird set up, and it works perfectly on my Android devices. It also does most functions on my Z10, but the push notification for the doorbell being pushed (i.e., the most important function) does not work. I've done some research and read that push notifications from Android apps are hit-and-miss. Does anyone here have an idea of how this might be remedied? Or does the developer need to do something, rather than one of us?
Thanks!

android notifications work fine on an android. on BB they are meh.
never tried that app when i had a BB

I believe somehow the app should be native to BlackBerry such that it connects with BlackBerry Hub
