All my messages were working fine until a few weeks ago when i could message everyone and receive messages.
Now one of my contacts can receive messages from me and can send messages successfully to me, on my phone the message shows up in notifications but whenever i go into the app they aren't there also, when i message my contact they receive the text fine but i can't see it on my phone.
The only odd thing i have seen is that the time stamp is the 8th Nov 2016, today is the 7th.
How can i fix this so i can see inbound and outbound messages?
