My foreground-sync about an hour ago before this post has stopped working completely. I can enable it but when I close the settings it then defaults to off. Before today I have been having intermittent issues with it, but I was able to turn it back on and continue as normal. But today is different. It's off, nothing has been changed settings wise.. no permissions were given for new apps.. nothing.. if someone can explain this.. that would be great.
Update: Still not working. I may have to factory reset to completely fix it as I have no clue what to do. I didnt install any applications or change any routines, it simply shut off during a text message and stayed off.
The foreground-sync associated with read receipts, delivery of text messages, etc. when your using the messages app, it is the reason why your messages are BLUE, and not GRAY, and it says "Delivered" beside it, -or- READ
