I am super exited about the new UnifiedPush notifications in /e/OS as I requested this feature two years ago! 
While there are ups and downs with /e/OS, there is still a constant improvement in the right direction and UnifiedPush is yet another liberation from a monopoly. Congratulations to the /e/OS team and thank you very much!
@Manoj could you please open again my old request so I can resolve it?
