IPhone 5c delayed notifications
Having an annoying error, iOS 7.0.4, using Straight Talk as a carrier but the bug happens on both wifi (home and work) and on lte. Basically push notifications don't come through sometimes if the screen is off. Other times it works fine, sometimes it's just delayed. Unlocked iphone 5c 32gb.
All app refresh and notification center settings are on appropriately. have done 4 factory resets and many more resets of just network settings (set up as new once, iCloud restore twice, connected to iTunes restore once). Most noticed due to delayed push notifications from the gmail app, active 911, and words with friends. Applecare no help so far. Am I the only one with this? I worry it's a problem since I have a different iCloud account from my iTunes account... Or is that nothing?
Help is appreciated.
