While I'm at school on wifi, both of the applications work fine. But when I'm at home, neither of them work despite the connection being fine as I am able to use the internet just fine. On the messages app the loading bar will reach close to the end and get stuck there and after a few minutes, I get the notification that the message was not delivered. I am not receiving messages either. Same situation with facetime, it'll try to connect as the whole ringing process happens but the other person doesn't receive the notification. Please let me know how I can fix this, thank you!
