I HATE THIS APP. Last time my friends couldn't chat with me, it was because the app was telling them that "this person is unavailable on messenger." I DIDN'T DEACTIVATE MY ACCOUNT. Why is this still appearing, and how come I can't chat on our groupchat because the messenger app says "Send Failed?" We limit how often you can post, comment, or do other things in a given amount of time. You can try again later. It's been more than 24 hours, but I still can't chat on our groupchat!
