I was up to sending a very long message, about 90,000 characters, to a friend, I tried several times but I got an error sending the message.
Finally, I think part of my message was sent because I could see the characters in my message list under my friend's name.
When I clicked the name to see my whole message it wouldn't load the message. And now I can't access any of my messages and I get this message from Facebook:
Sorry, messages are temporarily unavailable. Please try again in a few minutes.
How can I get access to my messages and conversations again?
