I did the same right now will update on results if it works than i dont have to struggle with delay on push notifications. Thank you!I had this same issue, I believe the issue is that some system apps (such as 'android system' and 'Google play services') are set to optimised battery settings, rather than unrestricted.
I changed many of them to unrestricted, and that seems to of fixed the issue.
I did also download an app called 'heartbeat fixer for gcm' , which may have also helped fix this issue.
Either way, the issue is not present anymore.
