Comment to Shoutbox block won't update in real-time
-
With the FB Messenger app also, I won't receive updates of new messages until my screen is on and then I will get notifications of all the messages I missed. I have an Xperia Z3 and it has a built in Stamina mode that does something similar to save battery but this feature is turned off on my phone so that would not be the culprit.
How would I find out why this is happening?
