No push notifications on AOSP rom.
I love my nexus 5 and I am trying to run an AOSP rom (tried both LiquidSmooth and CarbonRom) but for reasons unknown to me I can not get push notifications to work with apps such as Instagram, Snapchat, Twitter, and Google+ messages in hangouts. I believe these are all related to Google Cloud Messaging (GCM) for notifications.
I have tried different PA Gapps and Banks Gapps, PNF- Push Notification Fixer, different Kernels, clean installs, logging in and out of my Google Account, wiping the framework data.
I flashed a rom based on Stock and had no issues at all with notifications!!
Somebody for the love of god help me figure this out!
