When group text messages are sent to me while I am on a phone call, they do not download to the group text, but show from the individual person who sent them. Then, when I read the text, it will now show as read, so I have an unread text alert in Messages. The only thing I have been able to do to show it as read is to delete the entire conversation with the individual. This only hapens when I am on a phone call and group texts are being sent to me simultaneously. I am using the Messanger app (green).
