message

Hi, is it possible to recover a deleted message from a chat on whatsapp? The message deleted was an old message in a chat that was already read by both participants of the chat. It has been deleted only on one phone ("delete only for me" option). Is it possible somehow to recover it on the phone...

I've been texting to two people for months. All of a sudden it stopped working -- Message "Not Delivered". I can send and receive texts from each individual but not to the group. No phone numbers have been changed. Any help would be appreciated.
