I am running into an issue with my Galaxy S6 Edge. For the past week or so it seems that my push notifications do not work unless i am connected to WiFi. If i am not on wifi and i go to sync my gmail it will take a significant amount of time to refresh and show the new emails (anyway from 2-3mins+). Gmail will not do any push notifications nor will certain other apps. However Facebook and Messenger will work fine. I have updated all the apps, cleared cache for the apps, and even reset preferences for them. I also just finished doing a factory restore and am still having issues. Anyone else having LTE issues with their S6 Edge?
