I have the same problem as others using this app. Sometimes it takes hours or days for the person I sent message to recieve it. Also at times it wont allow me to send a picture due to cant resize the content. I'll try again and it sends. Sometimes I cand send multible pictures no problem. Sometimes when I open messages to read or send all my deleated messages are back. As in all of them. Then its back to normal when I try to show someone so they can help me find out if I changed a setting
